交—交变频器输出电压的基本重复周期

THE BASIC REPEATING CYCLE OF THE OUTPUT VOLTAGE OF AC—TO—AC FREQUENCY CHANGERS

本文给出交—交变频器输出电压基本重复周期中包含输出周期个数的计算公式,从而能够在使用交—交变频器的过程中,尽可能减小低频次谐波的影响,提高系统的性能。

In this paper, a formula is given. It can be used to calculate the number of outputcycle involved in a basic repeating cycle of output voltage of Ac—to—Ac frequency changers. This enable us to reduce the affection of the low—frequency harmonics and to improve the performances of an Ac—to—Ac frequency changer when use it.
