ABSTRACT:
An inverter supply voltage generator comprises an inverter supply voltage computing unit10, a voltage converter11and a battery12. The inverter supply voltage generator varies inverter supply voltage Vdc in synchronization with motor-application voltages Vu_pwm, Vv_pwm, and Vw_pwm. Thus, the degree of freedom of the switching operation of a PWM inverter13is increased, an inverter loss and the size of the PWM inverter13can be reduced, and its efficiency can be enhanced without deteriorating the driving efficiency of an IPM motor14.
