In this paper, a new signal-power integrated wireless GD concept is proposed. Unlike existing pulse transformer-based GD solutions, which directly transfers On/Off PWM edge signals from the control side to the MV power side, the proposed approach only transfers DC voltage levels through the shared WPT channel to generate PWM with indexes such as duty cycle and frequency locally at the MV power side, which is a brand-new isolated gate driving concept. The proposed design utilizes multi-frequency resonant networks and a shared WPT channel to transfer the DC voltage indexes and gate driving power simultaneously. The design method and experimental results are presented to verify the effectiveness and functionalities of the proposed isolated GD design.
