INVERTER, MOTOR, TRANSMISSION RATIO VARYING UNIT, AND AUXILIARY STEERING DEVICE

PROBLEM TO BE SOLVED: To provide an inverter in which an output current is not varied even if a power supply voltage is varied. SOLUTION: In the inverter 24 comprising an inverter circuit 60 for converting a DC into an AC by switching on/off states of upper and lower paired switching elements T1-T6,...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inverter in which an output current is not varied even if a power supply voltage is varied. SOLUTION: In the inverter 24 comprising an inverter circuit 60 for converting a DC into an AC by switching on/off states of upper and lower paired switching elements T1-T6, a circuit 56 generating a pulse signal for controlling on/off the switching elements T1-T6, and a section 50 for operating a command value delivered to the pulse generation circuit 56, a correction relation for determining a correction amount from a battery voltage is stored in a correction relation storage section 62, and a command value correcting section 54 determines a correction amount based on the correction relation and an actual battery voltage before correcting command values Vu, Vv and Vw* by using the correction amount thus determined. By such an arrangement, variations of motor currents Iu, Iv and Iw caused by variations in battery voltage are suppressed. COPYRIGHT: (C)2007,JPO&INPIT
