ROTARY ELECTRIC MACHINE DRIVING DEVICE |
摘要 |
A rotary electric machine driving device including: an inverter that is electrically interposed between a direct-current power supply and the rotary electric machine, and converts electric power between a direct current and an alternating current; a smoothing capacitor that is electrically interposed between the direct-current power supply and the inverter, and is connected between a positive pole and a negative pole on a direct-current side of the inverter; an inverter control unit that controls switching of a switching element of the inverter according to a predetermined switching frequency; and an inductance control unit that switches a direct-current side inductance between a positive pole of the direct-current power supply and a positive pole of the smoothing capacitor, according to the switching frequency, between a predefined standard inductance and a high inductance that is higher than the standard inductance. |
