Definition:

Synchronous rectification is a new technology that uses special power MOSFETs with very low on-state resistance to replace rectifier diodes to reduce rectifier losses. It can greatly improve the efficiency of DC/DC converters and there is no dead voltage caused by Schottky barrier voltage.

The basic circuit structure of synchronous rectification

Power MOSFET is a voltage controlled device, and its volt-ampere characteristics are linear when it is switched on. When the power MOSFET is used as a rectifier, the grid voltage must be synchronized with the phase of the rectified voltage to complete the rectification function, so it is called synchronous rectification.
