Abstract:
An engine generator, including a generator unit driven by the engine, a first power converter circuit, a capacitor, a second power converter circuit, a smoothing circuit, battery and a control unit. The control unit controls operation of the switching elements of the second power converter circuit so as to form a boosting circuit by the battery, the coil of the smoothing circuit, the switching element and the diode of the second power converter circuit, and the capacitor at starting of the engine.

Claim (Index 1):
An engine generator, comprising:\n an engine; a generator unit configured to be driven by the engine; a first power converter circuit configured to be electrically connected to the generator unit and to rectify power generated by the generator unit to DC current; a capacitor configured to be electrically connected to the first power converter circuit and to smooth DC current rectified by the first power converter circuit; a second power converter circuit configured to be electrically connected to the capacitor, to convert DC current smoothed by the capacitor to AC current and to have multiple switching elements and the multiple diodes connected one in parallel with each multiple switching element; a smoothing circuit configured to be electrically connected to the second power converter circuit, to smooth AC current converted by the second power converter circuit, to supply the smoothed power to an electrical load and to have a coil; a DC power source configured to be connectable to the smoothing circuit; and a control unit configured to control operation of the switching elements of the second power converter circuit so as to form a boosting circuit by the DC power source, the coil of the smoothing circuit, the switching element and the diode of the second power converter circuit, and the capacitor at starting of the engine.
