摘　　要：该设计根据电流控制型脉宽调制开关稳压电源的研究现状,提出了一个电流控制型脉宽调制开关稳压电源的设计方案。通过对其进行电压调整率及负载调整率的测试,结果表明:该电流控制型脉宽调制开关稳压电源在输入交流电压185V至250V时,可输出直流电压10V。该电源稳压效果良好、过流及短路保护方法合理、电压调整率和负载调整率均低于3%。According to the research status of current controlled pulse width modulation （PWM） switching power supply, a designscheme of current controlled PWM switching voltage stabilizing power supply is put forward in this paper. The voltage regulation rateand load regulation rate are tested. The results show that the output DC voltage of the current controlled PWM switching power sup-ply is 10 V when the input voltage is from 185 V to 250 V, and the output voltage of the current controlled PWM switching powersupply is 10 V when the alternate current （AC） voltage is from 185 V to 250 V. The voltage stabilizing effect of the power supply isgood, the over-current and short-circuit protection methods are reasonable, and the voltage regulation rate and load regulation rateare all less than 3%.
