Low Harmonic Drives: Driving Towards a Greener Future How Clean Power is Empowering the Automotive Industry

Over the past few decades, variable frequency drives (VFDs) have become widespread in industrial and commercial applications for their ability to control motor speed and torque. Traditionally, VFDs utilize pulse width modulation (PWM) techniques to vary motor voltage and frequency. However, PWM generates high harmonic currents that can damage motors, heat up transformers and power cables, and potentially cause voltage distortions on the utility grid. To address these challenges, a new generation of low harmonic drives has emerged based on advanced switching algorithms. What are Harmonics? In electrical systems, harmonics refer to sinusoidal voltages or currents having frequencies that are integer multiples of the fundamental power supply frequency, usually 50 or 60 Hz. Harmonics are produced by non-linear loads like adjustable speed drives that draw non-sinusoidal currents from the power source. The extra frequencies generated interact with the system impedance and generate losses, heating, vibrations, torque pulsations and can even cause misoperation of protective devices if sufficiently high in magnitude. Harmonics cause additional power losses in distribution transformers and overvoltages that reduce insulation lifetime. They can also interfere with communication lines. Traditional PWM Drives and their Harmonic Impact Traditional PWM VFDs employ insulated-gate bipolar transistors (IGBTs) or thyristors to rapidly switch the motor voltages on and off, generating quasi-square wave voltages to control motor speed. However, when these non-sinusoidal voltages are applied to the motor windings, they produce harmonic currents in the supply lines that are integer multiples of the fundamental supply frequency. Specifically, PWM drive techniques generate dominant 5th and 7th order harmonics that can propagate back into the utility system if not properly filtered. The harmonic currents not only stress motor windings but also increase I2R losses in the supply feeders and distribution transformers. Low Harmonic Drives can cause overheating in older transformers not designed for harmonics. Harmonic distortions also increase circulating currents within delta-wye grounded transformers. To mitigate these issues, dedicated harmonic filters need to be installed, increasing overall system costs. Excessive harmonics if left unchecked can even cause protective relays to malfunction. Advancements in Low Harmonic Drive Technology To address harmonic pollution from VFDs, innovative drive manufacturers have developed new low harmonic drive technologies based on advanced switching algorithms that naturally minimize the generation of lower order harmonics. Pulse-Density Modulation

One such technique is pulse density modulation (PDM) where the IGBTs are switched at high frequencies using narrower pulses compared to traditional square waves. By spacing the pulses closer together over time, PDM produces quasi-sinusoidal drive output voltages that inherently contain lower harmonics. PDM drives generate less than 5% total harmonic distortion (THD) without additional filters. Active Front End Drives

Another option is active front end (AFE) drives with a front-end rectifier consisting of IGBTs or MOSFETs instead of diode bridges. The AFE rectifier actively shapes the supply current waveform to follow the voltage waveform and provide near unity power factor without harmonics. AFE drives come with integrated DC chokes to absorb any remaining higher order harmonics internally, keeping them well below 5% THD.

The Benefits of Using Power Relays in Industrial and Commercial Applications

Power relays play a crucial role in various industrial and commercial applications. These devices help control large electrical currents with a smaller current, making operations safer and more efficient. In this article, we will explore the numerous benefits of using power relays, how they work, and their applications in different industries. What is a Power Relay? A power relay is an electrically operated switch that uses an electromagnet to move a set of contacts. When a small electrical current passes through the coil of the relay, it creates a magnetic field. This magnetic field pulls the switch contacts together, allowing a larger electrical current to flow through the relay. Once the small current is removed, the magnetic field dissipates, and the contacts return to their original position, breaking the circuit. Benefits of Power Relays 1. Safety One of the primary benefits of using power relays is safety. By using a small current to control a larger current, power relays reduce the risk of electrical accidents. This is especially important in industrial settings where large machinery operates on high voltage. By isolating the control circuit from the high-power circuit, relays protect operators and equipment from potential electrical hazards. 2. Remote Control Power relays enable remote control of electrical devices. This is particularly useful in commercial applications where equipment needs to be controlled from a distance. For example, in a large factory, machines can be turned on or off from a central control room, improving efficiency and convenience. 3. Automation In today's industrial world, automation is key to improving productivity and reducing costs. Power relays are essential components in automated systems. They allow machines to be controlled automatically based on certain conditions. For instance, a temperature sensor can trigger a relay to turn on a cooling fan when the temperature exceeds a certain threshold, ensuring that the machinery operates within safe limits. 4. Energy Efficiency Power relays contribute to energy efficiency by allowing precise control over electrical devices. Instead of running equipment continuously, relays can be used to turn devices on and off as needed. In particular, a high-current DC relay is essential for managing large electrical loads efficiently, further contributing to energy savings and system reliability. This reduces energy consumption and lowers operating costs. In commercial buildings, relays can be used to control lighting, heating, and cooling systems based on occupancy, further enhancing energy efficiency. 5. Longevity of Equipment By controlling the inrush current to electrical devices, power relays help extend the lifespan of equipment. Inrush current is the initial surge of current when an electrical device is turned on. This surge can cause wear and tear on components, leading to premature failure. Power relays can be used to gradually apply power to devices, reducing the impact of inrush current and prolonging the life of the equipment. How Power Relays Work To understand how power relays work, let's look at a simple example. Imagine you have a large industrial motor that needs to be turned on and off. The engine operates at high voltage, making it unsafe to control directly with a standard switch. Instead, a power relay is used. Control Circuit: A small switch or a sensor is connected to the control circuit of the relay. This circuit operates on a low voltage and current, making it safe to handle. Coil and Magnetic Field: When the control switch is activated, a small current flows through the coil of the relay. This creates a magnetic field around the coil. Switching Contacts: The magnetic field pulls a set of contacts within the relay together. These contacts are connected to the motor's high-voltage circuit. Power Flow: Once the contacts are closed, the high-voltage current flows through the relay and powers the motor. Deactivation: When the control switch is turned off, the current to the coil stops, the magnetic field disappears, and the contacts return to their original position, breaking the high-voltage circuit and turning off the motor. Applications of Power Relays 1. Industrial Automation In industrial automation, power relays are used extensively to control machinery and equipment. They can be found in assembly lines, robotic systems, and conveyor belts. By integrating relays with sensors and control systems, factories can achieve higher levels of automation, improving productivity and reducing human intervention. 2. Motor Control Power relays are widely used in motor control applications. They can start, stop, and protect motors from overload conditions. In industries such as manufacturing, mining, and construction, motors are essential for various operations. Power relays ensure that these motors operate reliably and efficiently. 3. Lighting Control In commercial buildings, power relays are used to control lighting systems. They can be connected to timers, occupancy sensors, and daylight sensors to automate lighting based on the presence of people and natural light levels. This not only enhances energy efficiency but also provides a comfortable and well-lit environment for occupants. 4. Heating, Ventilation, and Air Conditioning (HVAC) Power relays are integral components in HVAC systems. They control the operation of heating and cooling units, fans, and compressors. By integrating relays with thermostats and environmental sensors, HVAC systems can maintain optimal indoor conditions while minimizing energy consumption. 5. Power Distribution In power distribution systems, relays are used to protect electrical circuits from overloads and short circuits. They can quickly disconnect faulty circuits, preventing damage to equipment and ensuring the safety of the electrical system. Power relays are essential for maintaining the reliability and stability of power grids. 6. Renewable Energy Systems With the growing adoption of renewable energy sources such as solar and wind, power relays play a vital role in these systems. They are used to control the connection and disconnection of renewable energy sources to the grid, ensuring safe and efficient operation. Power relays also protect inverters and other components from electrical faults. Conclusion Power relays offer numerous benefits in industrial and commercial applications. They enhance safety, enable remote control, support automation, improve energy efficiency, and extend the lifespan of equipment. By understanding how power relays work and their various applications, businesses can leverage these devices to optimize their operations and achieve greater efficiency.

Protection Relay: An Important Electric Equipment

The components of transmission and distribution systems are exposed to overcurrent flow. When an electric current flows through a conductor in an electric power system in excess of what is intended, there is a risk of fire or equipment damage, as well as excessive heat generation. Overcurrent may be caused by short circuits, an excessive load, a transformer's inrush current, the start of a motor, poor design, or a ground fault. It is advised to use a ground fault locator. Tools like demand-side management, load shedding, and soft motor starting can be used to prevent overload when the system is operating normally.

This article discusses some tips for choosing the right protection relays:

The first issue concerns voltages that drive loads: The voltage rating of a relay must be greater than or equal to the voltage driving the load. Another critical factor is the frequency of the switched voltage. Because the alternating current fluctuates from positive to negative while crossing through zero, the switched voltage will fluctuate between the maximum voltage and zero. Conversely, because DC voltage is always at its maximum, each switch results in maximum contact wear. A 240 Vac relay is typically rated for only 24 Vdc.

 The required current varies depending on the type of load: The vast majority of loads do not draw a constant current. In reality, the current demand for most loads varies in a somewhat predictable manner.

  Avoid switching currents that are too low will ensure that the relay operates properly: A certain minimum current must be switched in order for a switch to operate properly. Because it burns off any contaminants that may have accumulated on the relay contacts, this current is also referred to as a wiping current. The contact material, the contact geometry, and the mechanical sliding of the contact surfaces all affect the lowest current that can be switched with reliability.
