For the PDF version of this article, click here. Protecting power transistors against overcurrent failure has always been a challenging issue in power circuit design. In order to protect against ...

Before addressing those requirements, let's review the basic concept of overcurrent protection. When current exceeds the rating of conductors or equipment — due to overload, short circuit, or ground ...

What's So Great About Overcurrent Protection? Understanding the overcurrent trilogy will help you protect your circuits. Circuit overcurrent protection encompasses overload, short-circuit, and ...

This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V.

By using dual bipolar devices in one case, the manufacturer nearly perfectly matches the two devices. Although this Design Idea describes a positive power supply, you can realize a similar ...

Requiring only a handful of inexpensive components, the circuit breaker in Figure 1 responds to both overcurrent- and overvoltage-fault conditions. At the heart of the circuit, D 2 , an adjustable, ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, sw… ...

Researchers have created a simple circuit using transistors that run on the chemicals that control living processes, rather than the electrons that usual transistors use. The result is a step ...
