摘　　要：高压变频器在矿井提升机等高压电动机上广泛应用。由于其功率大、电压等级高,应用场合重要,所以对其输入、输出的谐波含量、功率因数等要求很高。在高压变频器的输入端采用移相变压器实现多重化技术。通过对其输入、输出谐波的理论分析、仿真分析以及实际的应用分析,共同表明多重化技术的应用可使高压变频器达到谐波含量小,功率因数高的目的。High voltage inverters are widely used in high voltage motors. For example, the mine hoist and so on. Because its power is big, the voltage class is high, and the application situation is important, so it has a high demand to input har- monic, power factor, and so on. This paper we well use the phase shifting transformer in the high voltage inverter input to realizing multiple of technology. According to the theory, simulation, and actual application analysis of the input and out- put of harmonic wave, we can see by using multiple of technology we well reduce the harmonic and improving the power factor of the high voltage inverter.
