and frequency. In order to validate the conclusion and keep the stability and high efficiency of power transmission, the primary resonant current (exciting current) was regulated by switching between energy injection mode and free resonance mode, and a discrete-time quasi sliding mode control strategy was proposed. The variable structure model about the envelope of exciting current was constructed......
