Abstract

It is shown that the combination of phase and interphase voltages of a three-beam star allows the equivalent number of working zones of a three-phase rectifier to be increased by several times without complicating its circuit design. Using the structural synthesis method, a simple scheme of a three-phase rectifier with zone-phase control is obtained, in which the number of available combinations of output voltages to obtain the rectified voltage is greater than the initial number of zones. When regulating the rectified voltage using interphase voltages, the power factor of the rectifier is 0.92–0.956, which is comparable to the power factor of a three-phase uncontrolled bridge rectifier. The proposed principle of constructing zone-phase rectifiers allows any number of zones to be obtained, and the transition of the rectifier operating mode from one zone to another becomes smoother with an increase in their number.

增加三相交流整流器的工作区数量

摘要

结果表明，三束星形相电压和相间电压的组合可以使三相整流器的等效工作区数增加数倍，而不会使其电路设计复杂化。采用结构综合方法，得到了一种带区相控制的三相整流器的简单方案，其中可获得整流电压的输出电压组合数大于初始区数。使用相间电压调节整流电压时，整流器的功率因数为0.92-0.956，与三相不可控桥式整流器的功率因数相当。构建区相整流器的建议原则允许获得任意数量的区，
