A General Dead Time Compensation Method Based on Current Ripple Prediction and Pulse Delay Measurement for Voltage Source Inverter

This paper introduces a general dead time compensation method for voltage source inverter. By analyzing the dead time effect caused by the current freewheeling and switching delay, the precise dead time compensation can be implemented by reconstructing the actual phase current with the general current ripple prediction and pulse delay measurement. Simulation and experimental results are provided to validate the proposed method with good performance, and the proposed method can be extended to different topologies and modulation schemes.
