Here’s a handy little current source that’s often used to control the current flowing through a load. Find the equation that defines the i-Load current and account for non-ideal sources. The i-Load ...

Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

Automotive, industrial, and FireWire peripherals all call for high-efficiency, space-saving power supplies with high current capabilities at very high voltages. The problem is that high-voltage, ...

Diodes Incorporated has announced the introduction of the AP22913, a 2A single-channel, slew-rate-controlled load switch with true reverse current blocking for high-side load-switching applications.

The ability to turn on loads in a controlled manner is important in applications where the power budget is limited. Hard switching a load can cause the input power rail to droop and result in a fault.

The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure how ...

Here is a simple method for estimating the actual load on an electric motor without special equipment. But first, a word of caution: Some applications (e.g., a large forced draft fan) require more ...

A 480V, 3-phase, squirrel-cage motor is a common piece of equipment in many facilities. When sizing circuit breakers, fuses, and conductors for a general AC motor branch circuit, National Electrical ...

Constant current limiting circuits are commonplace, but sometimes a constant power limiting function is desired instead. This can be because downstream loads, like DC/DC converters, present a constant ...

Here is a nice hack you may find very useful if you have a cheaper bench power supply that supports constant current limit protection (CC mode) and the only way to set or check your max current limit ...
