级联型高压变频器供电特性研究

iming at the cascaded high voltage inverter which is used in the field of high power-high speed induction motor and combining with its technology and structure characteristics, a systematic simulation study including the phase shifting transformer rectifier module and the cascade inverter module is carried out, and the basic supplied character is obtained. The simulation results are coincident with the theoretical analysis and show that the cascaded high voltage inverter has excellent input and output characteristics and can meet the basic supply requirements of the high power-high speed induction motor. It provides some guidance to popularize and apply the cascaded high voltage inverter to the field of high power-high speed induction motor.
