Abstract: A big power laser switching source was designed, and its main circuit and control model were established.PFW was added based on PWM, and switching circuit between PWM, PFW and control circuit of external characteristic were designed, the control system fulfilled the higher request, and have double excellence of PWM and PFM. The open loop and closed loop were simulated by Matlab. The experimental results show that the design is correct.

Key words: power electronics, laser switching source, PWM, PFM
