一种新型稳压电源的研制

摘要

In the light of excessive switching device in AC stabilizer power supply and the complex circuit control,a new unipolar AC stabilizer chopper circuit topology is proposed.The circuit construction and control mode have lots of merits, simple,fast dynamic response ,little switching device,low harmonic wave content, little capacitance of filter capacitor and inductor, high output precision.The circuit adopts PWM chopper control mode, power factor on the system side is close to 1. Good simulation and model experiment demonstrate that the device has a large utility value.%针对目前交流稳压电源开关器件多,电路控制复杂的缺点,提出了一种新型单极性交流稳压斩波电路拓扑结构.该电路结构及其摔制方式简单,动态响应快;所用开关器件少,谐波含量小,可靠性高;滤波电容和电感容量小,输出精度高.通过采用PWM斩波控制方式,使系统侧功率因数接近于1.良好的仿真和样机实验结果表明该装置具有较大的实用价值.
