Abstract
A circuit for controlling an inverter which derives an alternating current output by driving complementarily two switching elements serially connected to a direct current power source into switching operation. It is required for one of the switching elements to turn on while the other of the switching elements turns off, and such a state as two transistors turn on concurrently must be avoided. For this reason, a control signal to be applied to the switching element of the inverter is passed through a delay circuit. According to the present invention, the delay circuit is comprised of a counter and a logic circuit, wherein the counter is supplied with clock pulses and at the predetermined count value the counter is made to generate an output. Upon generation of the output, a control signal is made to be supplied to the switching element of the inverter through the logic circuit.
