Synchronous rectification is a key technology enabling the development of switching power supplies toward higher efficiency, higher power density, and low-voltage high-current operation. By replacing diodes with low-resistance MOSFETs, it significantly reduces rectification losses, yet it also introduces challenges such as increased control complexity and higher costs.
With the advancement of semiconductor technologies and the popularization of integrated solutions, synchronous rectification has become the mainstream choice for modern high-efficiency power supply design. It is particularly indispensable in applications such as servers, communications, and fast charging for consumer electronics.
