Low-voltage circuit breakers are predominant in virtually every electrical power system. Several years ago, Shermco Industries surveyed NETA-accredited companies for the IEEE Electrical Safety ...

Racking in or out a power circuit breaker is simple, right? Although this task sounds pretty straightforward in theory, that’s not always the case. In fact, during years of field work related to ...

Ultra-low-voltage CMOS analog circuits operate from supply rails below 0.5 V to minimise power consumption in portable and energy-harvesting systems. Achieving high open-loop gain, flat frequency ...

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 ...

While searching for some SEPIC converters (https://en.wikipedia.org/wiki/Single-ended_primary-inductor_converter), I came across a popular power supply module that is ...

In an earlier blog post I did a teardown analysis of the XL4015 DC-DC Buck Converter module. I recently received an improved version of the same module. I purchased it from an online seller in China.
