采用变频控制实现交流调压的研究

Research on variable frequency control measure for AC voltage regulation

针对相控调压电路的缺点,提出了PWM双桥叠加型、交流斩波型和串联型等三种变频控制的交流电压调节电路。对其工作原理进行了对比研究,指出串联电压调节装置的性能价格比高于其它方式,是目前交流电压调节装置中较好的一种方案。

PWM double-bridge superposition regulator,AC chopping regulator and series voltage regulator are analyzed.It is pointed out that series voltage regulator has higher performance cost ratio and is the better plan for AC voltage regulation.
