Abstract
This paper presents energy saving of three-phase induction motor, which is operated in regenerative mode. In this mode, the energy flows back into DC link voltage and causes to occur high voltage in capacitor that may be destroy the capacitor and switching component such an IGBT. The proposed method presents connection buck converter circuit between the rectifier diodes and the inverter, to control the voltage feeding into the inverter by using two fuzzy controllers. The first fuzzy controller will be managing the switching duty cycle of buck converter. The second fuzzy controller, which provide to control the switching component of braking circuit. The second controller will be synchronized with the first controller to balance the energy of the capacitor. © 2006 ICASE.
