Abstract
A wireless power transfer system is disclosed. The wireless power transfer system includes a first converting unit configured to convert a first DC voltage of an input power to an AC voltage. Further, the wireless power transfer system includes a contactless power transfer unit configured to transmit the input power having the AC voltage. Also, the wireless power transfer system includes a second converting unit configured to convert the AC voltage to a second DC voltage and transmit the input power having the second DC voltage to an electric load. Additionally, the wireless power transfer system includes a switching unit configured to decouple the electric load from the contactless power transfer unit if the second DC voltage across the electric load is greater than a first threshold value.
