Abstract

PURPOSE: To expedite the stoppage of an inverter in power outage, by taking a control power source from DC bus voltage, starting decelertion regardless of how the operating condition is at the point of service interruption, and controlling its decelerating time in accordance with the then DC bus voltage value.
CONSTITUTION: An inverter device is composed of a power rectification section 1, a smoothing capacitor 2 and a power inversion section 3 and drives an induction motor 4. This control circuit is composed of (i) a power outage detecting means 18 comprising a voltage detection circuit 5, a power outage reference voltage setter 6, a comparator 7 and a hold circuit 8, (ii) an inverter control means 17 comprising an output frequency command decision circuit 10, a PWM signal makeup circuit 11 and a power inversion section drive circuit 13, to which an operational mode decision circuit 15 and an accelerating and decelerating time decision circuit 16 are added. When the second power outage signal is inputted, the mode decision circuit 15 outputs a decelerating mode signal regardless of whether the mode is. The time decision circuit 16 adjusts the decelerating time constant in comparing the present DC bus voltage value with the predetermined upper- and lower limit reference voltage values.
