Abstract
An inverter control circuit has a quantizer configured to generate a switching signal which changes over switches of a main circuit converting a DC voltage into an AC voltage, and a filter circuit configured to generate a signal having specific transfer characteristic by using a signal correlated with an output voltage of an LC filter which smooths the AC voltage and an instruction signal corresponding to a target value of an output voltage of the main circuit, wherein the quantizer generates the switching signal by quantizing an output signal of the filter circuit.
