A bidirectional wireless charger based on LCC-C resonance compensation is developed. The LCC-C resonance compensation circuit of this thesis is extended from the S-S compensation architecture which primary side using LCC compensation circuit and secondary side using series C compensation circuit. In the charging mode, the voltage source is converted to a current source (V-C) on the primary side, and the current source is converted to a voltage source (C-V) on the secondary side. In the discharging mode, the voltage source is converted to a current source (V-C) on the secondary side, and the current source is converted to a voltage source (C-V) on the primary side. This feature allows the output of bidirectional wireless power transfer to be a voltage source, and the open circuit caused by the damage of power converter on both sides or the load will not result in the voltage rise in the output resonance circuit in both of the charging and discharging modes. A hardware prototype of the bidirectional wireless charger based on LCC-C resonance compensation is designed according to the specification of SAE-J2954, the operating frequency point is 85k Hz, the output power is 3.7kW and the coil gap is 15cm. The experimental results verify that bidirectional wireless charger can achieve bidirectional wireless power transfer and constant current / constant voltage hybrid charging.
