开关式交流稳压电源的设计

Design of Switch-Mode AC Stabilized Voltage Supply

阐述一种较为先进的交流稳压电源设计方案。该设计方案采用脉冲宽度调制器、高速电子开关、高频电子变压器、LC滤波器等实现。与传统的晶闸管调角式交流稳压电源相比,该方案新颖独特,效率高,体积小,非线性失真小,是实现新一代交流稳压电源的全新方案。

An advanced design of AC stabilized voltage power supply is expounded in this paper.The pulse width modulator（PWM）,high-speed electronic switches,high-frequency electronic transformer,and LC filters was adopted to realize the design.In comparison with AC stabilized voltage supply of the traditional thyristor angle modulation mode,this scheme is of higher efficiency,smaller size,smaller nonlinear distortion and it is an entirely new design of AC stabilized voltage supply.
