Abstract
In this paper, an improved dead time compensation method which is concerned about dead time and extra time in Pulse-Width-Modulation(PWM) period is presented comparing the existing dead time compensation. The voltage drop across the switches are modeled excluding effect of stray capacitor. A low pass filter(LPF) is adopted for accurate detecting of current polarity. The method is based on Space-Vector-Pulse-Width-Modulation(SVPWM). All simulation results are presented using MATLAB and Simulink.
