Title:
POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2022/168290
Kind Code:
A1
Abstract:
The power generator of the present invention comprises: an engine; an electric motor that functions as a starter for starting the engine and also functions as an alternator for generating three-phase AC power by being driven by the engine; a rectifier circuit that is provided with a plurality of FETs for switching the energization state of each phase of the electric motor and rectifies the output of the electric motor; an inverter that converts the DC power output by the rectifier circuit to AC power and outputs the AC power to the load side; and a control means that controls the plurality of FETs. The electric motor is an IPM motor. When supplying the AC power to the load, the control means causes the electric motor to function as the alternator while boosting the output voltage of the electric motor by controlling the on/off of the plurality of FETs so that a braking force acts on the rotation of the electric motor.
