Reading more about inrush current control techniques now, all I knew before this was that you use Negative Temperature Coefficient parts to control it without affecting overall efficiency too much.

I've never had to design a board that drew much power, or didn't just use an off the shelf power supply. Power supply design is black magic so even major companies usually just buy certified open frame units to avoid redoing a ton of regulatory work, it's what's best for everyone. All the appliances at First Job just had a 24V Great Wall open frame units jammed in there, plus consumer 12V supplies for the network gear.

You can do some clever things involving having the NTC take itself out of the loop with a relay and a zener diode if you have really high efficiency targets to hit or you don't want to fry your NTC as the current picks up. I love these kinds of self-contained feedback tricks, they're super handy. And of course there's digital current controllers for high precision applications.

Figure 5 shows the relay circuit for a 1kW power supply. The relay is initially turned off. During power up, the input current flows through a 10Ω/10W cement resistor. Once the power supply is energized, a regulated bias voltage, 12V2, turns on the relay to minimize the power dissipation on the current-limiting circuit during normal operation.

Anyway. Reading specs it looks like there's a systematically higher inrush current in computer PSU's when you connect them to 230V, which is probably just Ohm's Law at work. A lot of supplies with really good 110V inrush limiting have utterly dogshit 230V inrush limiting.

An interesting problem I realize this might cause is that, because most tech reviewers are Americans with 110V, they won't pick this up as often. E.g. the highly recommended SF750 from Corsair has fantastic 120V inrush of ~30A but on 230W it's almost 80A, which would definitely trip a lot of home breakers.

What are the Limitations and Applications of Thevenin Theorem? 

Thevenin’s Theorem states that any linear electrical network can be replaced by an equivalent circuit consisting of a single voltage source in series with a resistor. This equivalent circuit accurately models the original network’s behavior as seen from a specific pair of terminals. 

Explaining Thevenin’s Theorem

In essence, Thevenin’s Theorem allows us to simplify complex circuits by finding an equivalent Thevenin voltage and Thevenin resistance. This makes circuit analysis more manageable and enables us to predict how the circuit will respond to different loads. 

Imagine you have a complex electrical circuit with multiple components like resistors, voltage sources, and current sources. Thevenin’s Theorem allows you to condense this complexity into a simpler representation of a Thevenin equivalent circuit while preserving the original circuit’s behavior between two terminals. 

To apply Thevenin’s Theorem, follow these steps: 

Identify the terminals: Determine the two terminals (let’s call them A and B) across which you want to simplify the circuit. 

Calculate Thevenin Voltage (V_th): Disconnect the load connected across A and B. Calculate the open-circuit voltage (V_th) across terminals A and B. 

Calculate Thevenin Resistance (R_th): Turn off all independent sources (voltage and current sources) and calculate the equivalent resistance looking back into the circuit from terminals A and B. 

Thevenin’s Theorem Statement and Proof

The statement of Thevenin’s Theorem can be summarized as follows: 

The formal statement of Thevenin’s Theorem is as follows: “Any linear electrical network containing independent and dependent sources can be replaced by an equivalent circuit consisting of a single voltage source (Vth) in series with a single resistor (Rth). This equivalent circuit is valid only at the terminals of interest. 

Thevenin’s Theorem Derivation

To derive the Thevenin equivalent circuit, we start by removing all sources in the original circuit and determining the voltage across the terminals of interest. Then, the circuit is simplified to find the Thevenin resistance. This step-by-step process results in the derivation of the Thevenin voltage and resistance. 

To derive Thevenin’s Theorem formula, we start by considering a complex circuit with multiple elements. By progressively simplifying this circuit, we ultimately arrive at the Thevenin equivalent circuit. The process involves finding the open-circuit voltage and the short-circuit current, which serve as the basis for determining Vth and Rth respectively. 

Finding Open-Circuit Voltage (Voc): We disconnect the load from the original circuit and measure the voltage across its terminals. This voltage is the open-circuit voltage. 

Finding Short-Circuit Current (Isc): We short-circuit the load terminals and measure the current flowing through the circuit. This current is the short-circuit current. 

Calculating Vth:The open-circuit voltage directly translates to Vth as there is no current flowing through the load. 

Calculating Rth: By applying Ohm’s Law (R=V/I ), we divide the open-circuit voltage (Voc) by the short-circuit current (Isc) to obtain Rth 

Thevenin’s Theorem Proof

The proof of Thevenin’s Theorem is based on the superposition principle and the linearity of circuits. By analyzing the behavior of the original circuit with different independent sources, we can demonstrate how the Thevenin equivalent circuit accurately represents the network. 

Thevenin Theorem Examples

Example 1: Consider a circuit with a voltage source of 12V and a resistor of 4Ω. By applying Thevenin’s Theorem, we can determine the equivalent voltage and resistance to simplify the analysis. 

Example 2: In a more complex circuit with multiple sources and resistors, Thevenin’s Theorem offers a straightforward way to predict the circuit’s behavior under different conditions. 

Limitations of Thevenin Theorem

While Thevenin’s Theorem is a powerful tool for circuit analysis, the following are a few limitations, 

Applicable only to linear networks (those obeying Ohm’s Law). 

Assumes networks are time-invariant (constant parameters over time). 

Might not be suitable for circuits with non-linear components like diodes or transistors. 

Major Applications of Thevenin Theorem

Here are a few major applications of Thevenin’s Theorem, 

Circuit design: Thevenin’s Theorem is used to simplify complex circuits during the design phase. 

Fault analysis: By applying Thevenin’s Theorem, engineers can identify faults and troubleshoot electrical networks more efficiently. 

Simulation and modeling 

System optimization 

Fault diagnosis

Current Shunt Resistors

When it comes to measuring current in an electrical circuit, one commonly used component is the current shunt resistor. Whether you're an electronics enthusiast or a professional engineer, understanding the function and importance of current shunt resistors is essential. In this article, we will dive into the world of current shunt resistors, exploring their purpose, working principle, and applications. What is a Current Shunt Resistor?

A current shunt resistor, also known as a shunt resistor current sensor, is a low-value precision resistor used to measure the current flowing through a circuit. Typically composed of a low-resistance alloy, such as manganin or constantan, current shunt resistors offer accurate current sensing capabilities.

The key principle behind current shunt resistors is "Ohm's Law." According to Ohm's Law, the voltage drop across a resistor is directly proportional to the current flowing through it. By measuring this voltage drop, and knowing the resistance value, the current through the shunt resistor can be calculated using Ohm's Law equation: I = V / R, where I is the current, V is the voltage drop, and R is the resistance value. Applications of Current Shunt Resistors

The current shunt resistor find applications in various domains, including:Power Monitoring: In power management systems, current shunt resistors are used to monitor the current flow in circuits, ensuring efficient operation and overload protection.

Shunt Resistor Current Sensor: A Reliable Solution for Precise Current Measurement

Current sensing is an essential aspect of various applications in industries, electronics, and power management systems. Accurate current measurement allows engineers to monitor and analyze the performance of electrical systems, ensuring their safety and efficiency. One popular method of current sensing is through the use of a shunt resistor current sensor. In this article, we'll explore what a shunt resistor current sensor is, how it works, and why it is a reliable solution for precise current measurement.

A shunt resistor current sensor is a device that measures the current flowing through a circuit by the voltage drop across a precise low-value resistor known as a shunt resistor. The shunt resistor is placed in series with the load or the circuit branch under measurement. As current flows through the shunt resistor, a small voltage drop proportional to the current is generated.

The principle behind a shunt resistor current sensor is Ohm's law (V = I * R), where V is the voltage drop, I is the current, and R is the resistance. By accurately measuring the voltage drop across the shunt resistor using high-precision instrumentation amplifiers or operational amplifiers, the current flowing through the circuit can be determined.

One of the key advantages of using a shunt resistor current sensor is its high accuracy and precision. Shunt resistors are available in low resistance values and with excellent tolerance and temperature coefficient specifications. This enables precise current measurement with minimal errors. Moreover, shunt resistor-based current sensing provides a linear relationship between the voltage drop and the current, making it easier to calibrate and interpret the results.

Another benefit of shunt resistor current sensors is their low insertion loss. Since the shunt resistor has a low resistance value, it causes minimal voltage drop and power dissipation in the circuit. This ensures that the circuit's overall performance is not significantly affected by the presence of the current sensor. Additionally, shunt resistor current sensors do not require any external power source, making them more cost-effective and easy to integrate into existing designs.

In conclusion, shunt resistor current sensors are reliable and accurate devices for measuring current in various applications. Their high precision, linear response, and low insertion loss make them an ideal choice for demanding current measurement requirements. Whether it's for power management, industrial automation, or electronics, the use of a shunt resistor current sensor ensures precise current monitoring and enhances the safety and efficiency of electrical systems.
