• Synchronous rectification is a new technology that uses special power MOSFETs with extremely low on-state resistance to replace rectifier diodes to reduce rectification losses. It can greatly improve the efficiency of the DC/DC converter and there is no dead-time voltage caused by the Schottky barrier voltage. Power MOSFET is a voltage-controlled device, and its volt-ampere characteristics are linear when it is turned on. When using a power MOSFET as a rectifier, the gate voltage must be synchronized with the phase of the rectified voltage to complete the rectification function, so it is called synchronous rectification. Synchronous rectification technology greatly reduces the rectification loss at the output end of the switching power supply, thereby improving the conversion efficiency and reducing the heat of the power supply itself.
