变频技术在交流调压中的应用

Study of AC Voltage Regulating Based on VF Technologies

分析了PWM双桥叠加型、交流斩波型和串联型3种变频型交流电压调节电路。对其工作原理进行了对比研究,指出串联型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。

In this paper, PWM double-bridge superposition regulator, AC chopping regulator and series voltage regulator were analyzed. It painted out that series voltage regulator had higher performance cost ratio and was the best plan for AC voltage regulation.
