VVVF逆变器系具有可变电压(Vari-able Voltage)和可变频率(Variable Fre-quency)的逆变器简称,它由GTO可挖硅构成。 GTO(Gate Turn Off)可控硅的特征是,正脉冲电流流经门极时即可导通;负脉冲电流流经门极时即可关断。将此GTO可控硅用于实际电路时,需要外部电路。用VVVF逆变器控制的电动机电压、电
VVVF inverters are short for Vari-able Voltage and Variable Frequencies inverters that are made of GTO-cut silicon. GTO (Gate Turn Off) The characteristic of thyristor is that the positive pulse current can be conducted when it flows through the gate, and the negative pulse current can be turned off when it flows through the gate. When this GTO thyristor is used in an actual circuit, an external circuit is required. Motor voltage controlled by VVVF inverter
