초록
This paper deals with the slip power recovery system using switch mode converter in the inverter DC side, which recovers slip power of induction machine to AC line with the aid of the boost converter. As a results, the motor speed can be controlled by the duty ratio of boost switch, not by inverter firing angle. This results that the reactive power produced by phase controlled inverter and diode rectifier can be greatly reduced and linear speed regulation can be obtained. Moreover, the harmonic components of line current caused by the commutation in inverter and rectifier can be considerably suppressed. Therefore, most of the problems in conventional system can be solved.
