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.

Passive Harmonic Filters: Key Advantages and Where They’re Used

In the modern changing industrial scenario, power quality management is now a priority for companies in all industries. With the growing application of variable frequency drives (VFDs), LED lighting, computers, and other non-linear loads, harmonic distortion in power systems is gaining prevalence. To mitigate these issues, engineers deploy different solutions, one of the most common being passive harmonic filters. These filters have proven to be reliable and effective, particularly in environments with predictable load conditions. In this blog, we’ll explore the concept of passive harmonic filtering, its benefits, how it differs from other solutions like active harmonic filters, and where it is best applied.

What Are Passive Harmonic Filters?

Passive harmonic filters are equipment used to minimize harmonic distortion in an electric system via the utilization of passive components of predominantly inductors, capacitors, and resistors. The components are connected in such a manner as to absorb or redirect certain harmonics but transmit the fundamental frequency (usually 50 Hz).

Unlike active harmonic filters, which dynamically cancel harmonics with power electronics and digital controls, passive filters are fixed-tuned to particular frequencies. This is advantageous in installations where the harmonic spectrum is well understood and comparatively constant.

Major Advantages of Passive Harmonic Filters

1. Cost effectiveness

One of the greatest benefits of passive harmonic filters is that they are cost-effective. They are much cheaper than active harmonic filters to purchase, as well as maintain over time. For buildings that have a limited budget or that do not require dynamic filtering, passive filters are an effective solution.

2. Easy Installation and Design

Passive filters are simply designed and require no complicated configuration or digital interfaces. This is a plug-and-play filter that makes it easy to integrate into current electrical installations. It is the simplicity of the design that makes it a good choice for facilities that do not have specialized technical personnel.

3. Dual Functionality with Power Factor Correction

Most passive harmonic filters are also Power Factor Correction devices. Enhancing the power factor reduces the consumption of reactive power and decreases the cost of electricity.

 This two-in-one design reduces system architecture and saves space.

4. Low Maintenance

Because these filters contain only passive components, they have fewer failure points and need little maintenance in the long run. This reliability means extended operational life and reduced downtime.

5. Automatic System Support

As part of automatic power factor correction systems, passive filters make overall energy efficiency possible. These systems adjust power factor automatically and handle harmonics as well, providing an end-to-end power quality solution.

Passive vs Active Harmonic Filters

The decision between passive harmonic filters and active harmonic filters will be based on the system's complexity. Passive filters are tuned to address specific frequencies, whereas active filters are capable of sensing and neutralizing a broad spectrum of harmonic currents in real-time. Active harmonic filters are well suited to dynamic loads where load conditions are continuously changing, like data centers or advanced manufacturing facilities. In stable loads like water treatment plants or HVAC systems, passive filters are a cost-effective and effective solution.

Role in Automatic Power Factor Correction Systems

Automatic power factor correction systems are employed to monitor the power factor of electrical installations continuously and correct them. They are required in industries that go through fluctuating load conditions during the day. When these systems are made to incorporate passive harmonic filters, they improve overall efficiency not only by compensating for the power factor but also for filtering harmonics. This is particularly valuable in manufacturing facilities and commercial offices where both power factor and harmonic distortion must be controlled at once.

Where Are Passive Harmonic Filters Used?

1. Industrial Manufacturing Plants

Applications with fixed-speed motors and drives tend to have harmonics because of the steady nature of their loads. Passive filters are best in such cases, as the harmonics are deterministic and controllable with fixed-tuned solutions.

2. Water Treatment Plants

Such plants tend to have constant, non-linear loads from compressors and pumps. Passive filters ensure clean power supply and continuity of equipment operation.

3. Commercial HVAC Systems

Heating, ventilation, and air conditioning units may produce substantial harmonics, particularly when more than one unit is operating at the same time. Passive filters can be used to stabilize voltage and safeguard delicate control systems.

4. Telecommunication Infrastructure

Ongoing operation of power supplies and rectifiers makes the use of passive filters beneficial at telecom sites to suppress electrical noise and enhance network equipment reliability.

5. Educational and Government Buildings

These types of facilities may not necessarily experience high variation in their electric loads. An arrangement of Power Factor Correction combined with harmonic filtering via passive filters will guarantee that there is conformance to utility requirements and lessened energy expenditures.

Benefits of Power Quality Strategy

Although the passive filters in themselves can provide significant improvement, they tend to be most effective as part of an overall strategy which might incorporate automatic power factor correction units as well as, where required, active harmonic filters.

For instance, in a layered strategy:

These filters work best in eliminating harmonics with fixed, known frequencies.

Active filters deal with dynamic, variable harmonic loads.

APFC panels control real-time Power Factor Correction for optimal energy consumption.

This multi-layered configuration allows both power quality compliance and sustained equipment dependability.

Selecting the Proper Solution

Picking the right filter is based on a good grasp of your load characteristics. Passive solutions are generally utilized in eliminating specific fixed-frequency harmonic disturbances. This identifies the form and degree of harmonic distortion and leads to making a decision about passive harmonic filters versus active harmonic filters.

Final Thoughts

With the energy landscape growing more complex by the day, harmonic management can no longer be a nicety; it has to be a necessity. Passive harmonic filters offer a low-cost, low-maintenance solution for removing harmonic distortion and ensuring power quality, especially in controlled-load environments.

They also include the added advantage of Power Factor Correction to minimize energy losses and utility penalties. When integrated with automatic power factor correction systems, they provide an even more potent toolset for optimizing system performance. While active harmonic filters are still the first choice in dynamic, high-frequency harmonic suppression, passive harmonic filters remain the most reliable and cost-efficient solution for most industrial and commercial applications.
