摘　　要：基于串联电容法和并联电容法提高两台同工况三相异步电动机功率因数的原理,推出串联电容法和并联电容法所需电容量之间的关系,从而证实了用串联电容法提高电动机功率因数时,在一定条件下所需电容量较小,且能减小电动机启动电流。The series capacitor method and the shunt capacitance method were used respectively to increase the power factor of two three-phase asynchronous motors with the same working conditions, and based on that the needed capacitance in the two methods were both obtained. Consequently, it is concluded that the series capacitor method needs less capacitance than the other method, and the start-up current can also be reduced.
