无线电能传输中推挽式并联谐振逆变器的开关开/关软开关自动谐振调谐

This letter proposes the tunable resonant tank and its control method for push–pull parallel-resonant inverter in wireless power transfer application. The parallel tuning capacitor is controlled using pulsewidth modulation, and its duty cycle is determined by the sensing of drain voltage waveshape. Soft switching is ensured at both the turn-on and turn-off for every switches in the proposed invert...
