摘要
高压变频器是指输入电源电压在3kV-10kV的大功率变频器。由于其功率大、电压等级高,应用场合重要,所以对其输入谐波、功率因数等要求很高。因此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。
The high voltage inverter is the input power supply voltage of 3 kV- 10kV＇s power inverter. Because its power is big, the voltage class is high, the application situation is imporlant, it having a high demand to input harmonic, power factor, and so on ,Therefore using phase-shifting transformer to achieve rectifier multiple of the high voltage inverter. The highvoltage converter can reduce the input harmonic, and improve power factor.
