Abstract
A mobile side circuit of a wireless power transmission system comprises a mobile side resonant circuit inductively coupled to a stationary side resonant circuit of the wireless power transmission system. A mobile side control circuit is adapted to change the operative mode of a mobile side rectifier upon occurrence of a failure state in the mobile side circuit. The present invention ensures a safe operation of the wireless power transmission system while effectively avoiding damage to the mobile side circuitry upon occurrence of a failure state at the mobile side.
