Voltage clamps for protecting low-voltage dc circuits require a new approach to circuit design. Many commonly used voltage clamps were built for systems of 5 V or higher, but lower-voltage systems ...

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 ...

In this post I will try to gain some insight into the electronics of a cheap PWM Power MOSFET Module. The module under the spotlight is the pretty common FR120N MOSFET Control Module which is a simple ...

Low-voltage CMOS analog circuit design has emerged as a critical area of research, driven by the dual imperatives of energy efficiency and high-performance signal processing. This discipline focuses ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

The distribution system, a key subset of the overall electric grid, provides power to residential, commercial and industrial customers. Voltage and reactive power management and control have been done ...
