Abstract:
An inverter control device drives one of the two switching circuits with a fixed conduction width and changes the control method of the other switching circuit between pulse-width modulation, phase control method, and drive signal width control method by phase control method according to an output state, to implement highly accurate control at low output while suppressing heat generation of a switching element.
