Dead-Time Compensation Method Based on Current Ripple Estimation

  title={Dead-Time Compensation Method Based on Current Ripple Estimation},
  author={Tomoyuki Mannen and Hideaki Fujita},
  journal={IEEE Transactions on Power Electronics},
This paper discusses the voltage error caused by the dead time in voltage-source PWM converters. The theoretical analysis in this paper derives the nonlinear voltage error paying attention to the parasitic output capacitance in each switching device. The analytical result reveals that the turn-off current or the switching current ripple strongly affects the voltage error. In addition, it is clarified that the conventional compensation methods based on linear and three-level approximation are… CONTINUE READING
