ABSTRACT:
To provide a cheap inverter which uses a single digital microprocessor and can execute a current control and a maximum power control without changing a design of a hardware even for any switching device or solar cell, there is provided a control apparatus of an inverter for converting a DC electric power into an AC electric power by using a switching device, wherein the control apparatus is constructed by an inversion discrimination circuit for receiving an output current or an output voltage and a reference signal and for discriminating whether a switching state of the switching device should be inverted or not and a gate pulse signal forming unit for changing the switching state of the switching device in response to an inversion request signal which is outputted from the inversion discrimination circuit. The gate pulse signal forming unit has a CPU for forming a gate pulse signal by an interrupting process by using the inversion request signal as an interruption control signal.
