We use batteries to supply power in several projects. The chemicals contained in the battery are converted into an electrical current, which in turn makes the battery contain the potential energy.

In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

What are HVICs? High-voltage integrated circuits (HVICs) translate low-voltage control signals to levels that are suitable for driving power switches in high-voltage applications. HVICs also can ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...
