Abstract

PURPOSE: To obtain an inverter apparatus which can continuously operate without stopping a load even in an overload range by driving an inverter by the patterns of exclusive output voltage and frequency in the overload range.
CONSTITUTION: An inverter 2 converts an AC input from an AC power source 1 into a DC, and again converts the DC into an AC to drive an induction motor 3. When the operation of the inverter 2 is shifted from the normal load range to an overload range, the current of the motor 3 increases to gradually reduce the voltage applied to the inverter 2. At this time, a high level signal is output from a comparator 10 for comparing the output of a voltage detector 9 for detecting the voltage applied to the inverter 2 with a reference voltage, a microcomputer 11 outputs a signal of exclusive voltage and frequency characteristic to the inverter 2 in response to the signal. Thus, the high voltage is applied to the motor 2 to reduce the current flowing to the motor 3, and the motor 3 is continuously operated.
