应用PWM技术的大功率高频开关电源的研制

Researching and Making of Ample Power Switching Supply Using PWM

采用新型的电力半导体器件IGBT,新型非晶态软磁性材料,并采用PWM脉宽调制技术组成的大功率开关电源比之传统的可控硅移相式稳压电源有较多优越性:体积小,转换效率高,动态响应好,谐波分量小,对电网造成的污染小。

Compared with the traditional SCR phase-shifted regulated power supply, using new type of power semiconductor, non-crystalline state magnetic material and pulse width modulation technology, ample power switching supply has many advantages: small volume, high converting efficiency, good dynamic performance, small harmonic component and small pollution to AC supply.
