摘　　要：设计了一款反激式开关电源,依据理论计算出补偿器参数,通过实验调试证明计算参数能够使环路稳定,并接近于优化参数。This paper analyses the zero-pole of common links and three series of error amplifier＇s features and usage, expounds the system design methods. Then design a flyback SMPS, calculate the compensation parameters in accordance with the analysis, experimental resuhs show the calculation parameters can keep the loop stable and approach the optimized value.
