摘要
介绍一种新型的交流稳压电源,给出了交流稳压电源的工作原理和控制电路。该电路将PWM脉宽调制技术与动态调节电解电容器补偿有机结合在一起,利用电力电子元件中的自关断元件控制无极性半导体电解电容器进行充放电来达到动态调节补偿电压。
A new type of AC stabilized voltage power supply was introdted, the operative principle and control circuits of AC stabilized voltage power supply were given below. The circuit organically combined PWM pulse width modulation technology with dynamic adjustment electrolytic capacitor compensation, and it controls nonpolar semiconductor electrolytic capacitor charging and discharging by self-turn-off device of the power electronics, with a result of the dynamic adjustment of the offset voltage.
