Abstract A novel online adaptive dead-time elimination method is presented in this paper for PWM voltage source inverters, based on the analysis of dead-time effects and the principle of dead-time elimination. Tracking the load change on-line and determining dynamically the current direction, the zero current zone and the non zero current zone of the output inductor are precisely distinguished and the optimal width of the zero current zone is adaptively calculated. Furthermore, the dead-time effects are completely eliminated in the whole sinusoidal modulation cycle. In comparison with traditional dead-time compensation and elimination methods, the proposed method can significantly restrain the output distortion in the zero current zone and reduce the low-frequency harmonic contents and THD. The simulation and experimental results demonstrate the validity and practicability of the proposed method.
