Besides switching at a fixed frequency for Flyback converters, quasi-resonantmode is widely used due to its lower switch-on losses and better EMI performance.
On the basis of comparing with power supply of full bridge voltage mode, the authors bring forward the full bridge series resonantmode applied in the pulsatile laser power supply.
在与全桥电压型充电方式激光电源比较的基础上，提出了一种谐振充电式脉冲激光电源。

The results proved that the improved resonantmode load current is close to sine wave. The energy transfer efficiency of transformer is improved by 3 percent, and the EMI is decreased.
