Abstract

In voltage-source inverters (VSIs), deadtime is used to prevent going straight through over switching devices. However, the existence of the deadtime will distort the output phase current, which degrades the performance of VSIs. The traditional drive pulse width correction is developed by analyzing the effects of deadtime on a pulse by pulse basis and correcting each pulse according to the polarity of phase current. Given that common sampling-based deadtime compensation (DTC) methods are often affected by current ripple. In this paper, we introduce a novel DTC method for VSIs that eliminates the effect of current ripple and improves the accuracy of DTC.The proposed strategy reconstructs the current values at the turn-on and turn-off moments of the drive signals for each phase in real-time by calculating the current ripple trajectory. Simulations and experiments are provided to demonstrate the effectiveness of the proposed methodology.
