摘　　要：介绍了利用TOPSwitch构成的反激变流器,并从传递函数补偿的角度分析了反馈电路的设计方法。通过反馈电路结构和参数的调整,变流器的输出电压纹波大幅度减小,抗干扰性能得到了加强,效率有所提高。The flyback switching power supply based on TOPSwitch is introduced. Through analysis of the trans-function of compensation the designing method for the feedback circuit is presented. By adjusting parameters of circuit, the ripple of the output voltage has been decreased greatly, the performance of anti-disturbance and the efficiency have been improved.
