Abstract
PURPOSE: To raise the economical efficiency of an inverter, by detecting the output voltage of a voltage control amplifier after a load is already started or when the output voltage is not controlled and by short-circuiting a chopper circuit through a mechanical switch or an electric valve to operate the chopper circuit for a short time.
CONSTITUTION: When a load motor 6 is started, the output voltage V of the chopper circuit 2 is controlled in proportion to a speed reference SR for a time from t0 to t1 and the frequency of the inverter is also controlled in proportion to the speed reference. When the voltage of the chopper circuit 2 is saturated at the time t1, the output voltage VA of the voltage control amplifier 12 rises sharply to increase the voltage of the chopper circuit. The output voltage VA is detected by a level detector 14 to actuate a contactor 15 to short-circuit the chopper circuit 2. After the time T1, only the frequency of the inverter increases in accordance with the speed reference SR. Then, the speed of the load motor 6 is regulated in a known constant power control range.
