Abstract

PURPOSE:To smoothly start an induction motor by controlling a specific pulse width only at the starting time irrespective of a voltage command value, thereby reducing the output voltage and suppressing the jump of a current. CONSTITUTION:A DC power source having no voltage controlling function is connected to a pulse width control type variable voltage and variable frequency inverter 4 through a filter made of a reactor 1 and a capacitor 2 to drive an induction motor 5. The inverter 4 is controlled by a circuit which compares the carrier voltage waveform controlled in frequency by the frequency command signal with a variable voltage level varying with a voltage command, and is controlled to reduce the output voltage irrspective of the voltage command signal only for the specific pulse at the starting time. Accordingly, since it can reduce the fundamental voltage at the starting time, the motor 5 can be smoothly started.
