摘要： A wireless power transfer system (300) is disclosed. The wireless power transfer system (300) includes a first converting unit (204) configured to convert a first DC voltage of an input power to a first AC voltage. Further, the wireless power transfer system (300) includes a contactless power transfer unit (208) configured to receive the input power having the first AC voltage from the first converting unit (204) and transmit the input power. Also, the wireless power transfer system (300) includes a second converting unit (210) configured to receive the input power from the contactless power transfer unit (208) and convert the first AC voltage of the input power to a second DC voltage. Furthermore, the wireless power transfer system (300) includes a switching unit (212) configured to regulate the second DC voltage across the electric load (232) if the second DC voltage across the electric load 232 is greater than a voltage reference value (Vref).
