Bilateral asymmetric voltage control method of bidirectional wireless power transmission system

The invention discloses a bilateral asymmetric voltage control method of a bidirectional wireless power transmission system. The method comprises the steps of obtaining a phase of an alternating current side port current of a first full-bridge converter, and a direct current side voltage and a direct current side current of the first full-bridge converter; determining a total pulse width angle ofthe alternating current side voltage of the first full-bridge converter according to a voltage stabilization or constant current requirement; determining switching-on and switching-off moments of a switch tube of the first full-bridge converter, and driving the switch tube based on that; sending required parameters to a primary side controller; determining a value range of the total pulse width angle of the alternating current side voltage of a second full-bridge converter in order to realize zero-voltage switching, and selecting an optimal value of the total pulse width angle of a primary side excitation voltage in t
