Dual-voltage output generator motor

摘要

PURPOSE:To provide a generator motor system which can output two high and low voltages while suppressing fluctuation in the rectified output voltage. CONSTITUTION:During the torque assist period of an engine, semiconductor switches S1,..., S6 in an inverter circuit 4 are turned ON/OFF to apply an AC three-phase voltage to a generator motor 2 and during the charging period of a high voltage power storage means 8, semiconductor switches T1,..., T3 of a low voltage three-phase full-wave rectifier 9 are turned OFF. Consequently, a generated voltage is rectified through high voltage three-phase full-wave rectifiers D1,..., D6 and during the charging period of a low voltage power storage means 10, the semiconductor switches S1,..., S 6 in the driver circuit 4 are turned OFF and an ON voltage is applied to the semiconductor switches T1,..., T3 of the low voltage power storage means 9.
