Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

Fully digital architectures offer deeper visibility into the power supply’s performance as well as the health of the overall application.

This white paper reinforces the notion that digital power supplies are here to stay and there has not been a better time to make the switch to digital. The AC-DC Reference Design from Microchip is a ...

History Lesson Single-phase power supplies have been a power industry norm for ESPs for more than 60 years. Analog automatic voltage control and silicon-controlled rectifiers were the single-phase ...

The WBQ series features a standard input voltage of 208VAC, three-phase, with an optional 400VAC version also available, making it suitable for global use. The unit also features ripple levels as low ...

Greg Evans, CEO of WelComm Inc. and PSMA Marketing Committee member, contributed to this article. For nearly two decades now, digital implementations of power-supply designs have been implemented in ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

In an effort to bring reliable electricity supplies to emerging regions and remote island communities, Panasonic has developed an expandable, portable, self-contained photovoltaic system. The "Power ...

This three-part series describes how to properly test a DC/DC power supply, and ensure that it works reliably over various operating conditions. This series is intended to provide the designer with a ...
