摘　　要：高压变频器是指输入电源电压在3—10kV的大功率变频器。由于其功率大、电压等级高，所以对其输入谐波、功率因数等要求很高。采用移相变压器实现高压变频器的多重化整流，可使高压变频器的输入谐波减小，功率因数提高。对容量为630kVA，36脉波移相变压器的电流、匝数参数进行设计，并对多重化整流电路进行谐波和仿真分析，为工程实践提供依据。High voltage inverter refers to high-power inverter whose input power supply voltage is 3 - 10kV. Because its power is high and voltage high, its input harmonic and power factor are required to be high. Use the phase-shifting transformer to achieve multiple rectifier of high voltage inverter, it can make the input harmonic reduce and power factor increase. The current and turns parameters to 36 pulse phase-shifting transformer of 630kVA are designed. The harmonic and simulation for the multiple rectifier currect are analyzed. It gives a basis for project practice.
