【Abstract】 Aimed at the influence on the inverter output voltage caused by the PWM inverter dead-time, one dead time compensation strategy is proposed. This scheme utilize the current vector space angle to judge the three stator current polarity, deduce the three stator voltage compensations. The experiments demonstrate the validity of the proposed shceme.更多还原
