Abstract

In this paper, the effect of dead-time in a single phase wireless power transfer system (WPT) between the complementary switching pulses of the inverter leg is discussed in detail. The dead-time is always provided between the complementary switching pulses in the inverter leg to avoid the short-circuit of the input dc source. In WPT systems, high-frequency (HF) operation is desired to reduce the size of the passive components. As the frequency of operation increases, the dead-time effect becomes significant and must be addressed appropriately. This paper presents the analysis of the dead-time effect in the wireless power transfer system for an electric vehicle (EV) battery charging application. The operating waveforms for the given operating condition of the phase-shift angle and the power-factor are presented and the phenomenon of voltage polarity reversal (VPR) or notch is discussed. The effect of the notch on the fundamental component of the voltage is presented and the effect of the notch on the BMW i3 battery charging profile is evaluated. The theoretical analysis of the dead-time is verified using simulation results in PLECS.
