Abstract
- This paper proposes a wireless power transfer system using a series compensator GCSC (gate‐controlled series capacitor) as a primary side capacitor. The GCSC is a circuit module that functions as a series variable capacitor by controlling semiconductor switches. The advantage of applying the GCSC to the primary side capacitor is that it provides controllability of the output power factor for a high‐frequency inverter. Therefore, optimum operation of the high‐frequency inverter can be achieved irrespective of the coil parameters by controlling the output power factor. Experimental results with a 1 kW laboratory prototype confirmed that the proposed system can achieve optimum operation and high efficiencies of the high‐frequency inverter. [ABSTRACT FROM AUTHOR]
