In this paper, the novel on‐off modes including 12 conduction states is presented for H bridge in one switching period. Based on the novel on‐off mode, the dead‐time elimination pulse width modulation (PWM) is presented with good switching times sharing effect. The digital judgment method of output current polarity is proposed for the dead‐time elimination PWM. The PWM generator is integrated in the field‐programmable gate array. Simulation and experimental results are provided to validate that the proposed PWM can be applied to H‐bridge voltage source inverter with good performance. © 2021 Institute of Electrical Engineers of Japan.
