Summary/Abstract: Synchronous straightening is a technique for improving the efficiency of power converters in power electronics. It consists of a parallel connection of a diode and a transistor (usually a powerful MOSFET). In this way, a rectifier characteristic is obtained, without a significant voltage drop in the forward direction associated with the diodes in the on state. As a result, power supplies run cooler and more reliably and save significant energy costs. The design of converters at high power shows that the use of synchronous rectifier gives a significant improvement in the efficiency of the whole device. The aim of this article is to study and compare the energy characteristics of bridge and synchronous bridge rectifiers used in AC / DC converters.
