AC-AC converter technologies have become pivotal in modern power systems owing to their capability to directly transform alternating current from one voltage and frequency level to another without ...

Viper31 is a mains voltage converter for ac-dc power supplies from STMicroelectronics which allows PSUs to be constructed that consume only 20mW no-load at 230Vac, while delivering up to 18W when ...

TRACO Power says its new TMR 8WI series of converters is designed to be compact, efficient, and reliable in extreme conditions.

The demand for smaller, lighter, and more efficient AC/DC USB power delivery (PD) chargers is always a challenge for power-supply design engineers. Below 100 W, the quasi-resonant flyback is still the ...

A power converter’s efficiency (AC-DC, DC-DC, or Buck) is determined by comparing its input power to its output power. More precisely, the efficiency of the converter is calculated by dividing the ...

International Rectifier, IR introduced the IR11672A SmartRectifier™ IC with advanced Minimum On Time (MOT) protection circuitry for energy-efficient AC-DC power converters for laptops, LCD and PDP ...
