Title: Engine type power generating device
Inventor: TAKAKADO YUZO
IPC: H02J9/06
Filed: 1990-11-30
Abstract: PURPOSE:To realize a low cost and a compact size of the device by conversion- driving a rectifier circuit in the reverse direction so as to chopper-drive a switching element between a reactor of a convertor circuit and one side terminal of a smoothing capacitor, at the engine starting. CONSTITUTION:When an AC generator AC is driven as an engine starter, all the transistors QI1 to QI4 of a reverse converter circuit are kept in OFF condition, and an ON instruction S4 is given from a control circuit 5 to close a switch SW, prior to the starting. As a result, an electrolytic capacitor CD is charged to the polarity showen in the figure from a battery BATT through a diode D2 connected to a reactor LO and a transistor QI3, and the terminal voltage of the electrolytic capacitor CD is raised up to the voltage of the battery BATT. In such a way, after the battery BATT is charged initially, only the transistor Q14 of the transistors QI1 to QI4 of the reverse converter circuit is driven ON/OFF to carry out a boosting chopper operation.
