Electronic equipment uses predominantly positive voltage rails for power; occasionally, some negative voltage rails are also used. For this reason, negative (or inverting) output DC-DC converter ...

There are standard techniques to generate negative output voltages, and there are well-known approaches to dynamically adjust an output voltage. The missing link that I hope to address in this article ...

High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...

Two Solarlytics units installed next to a DC combiner. DC-DC converters are one option for tackling the issue of voltage collapse. Image: Solarlytics. As solar plants age and face varying ...

This power-management tip introduces the two different circuits for a positive-to-negative voltage conversion and a negative-to-positive voltage conversion. However, there are times when a voltage ...

It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...

There comes a time in every hardware hacker’s career during which they first realize they need a negative voltage rail in their project. There also comes a time, usually ~10ms after realizing this, ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.
