Abstract
In an inverter generator having a generator unit including three phase windings driven by an engine, a converter having multiple switching elements and configured to convert alternating current outputted from the generator unit to direct current, an inverter configured to convert direct current outputted from the converter to alternating current and output the alternating current to a load, and a converter control unit configured to determine PWM control ON-time period and drive the multiple switching elements so that inter-terminal voltage of direct current outputted from the converter stays constant with respect to increase/decrease of the load, the converter control unit is configured to detect, with respect to voltage waveforms occurring in the three-phase windings in cycle (t−n), crossing angle between voltage waveform of one phase and voltage waveform of a phase adjacent thereto and to drive the multiple switching elements of either the one phase and the adjacent phase in cycle (t) such that the detected crossing angle is included in the PWM control signal ON-time period.
