| Abstract: | The paper analyzes the dead time effects of the PWM voltage sourse inverter.Based on the analysis of sev-eral normal compensations,a modified predictive current control is introduced that compensates the voltage loss due to dead time and reduces the zero current clamp problem caused by dead time.The validity and feasibility of the proposed al-gorithm are confirmed by experimental implementation. |
