NOVELTY - The device has a secondary coil arrangement (22) adapted to provide an electrical alternating voltage during a magnetic alternating field launching between two terminals. A rectifier (21) is laid out to rectify the alternating voltage of the secondary coil arrangement. Switching arrangements (S5, S6) are laid out to electrically interconnect the two terminals of the secondary coil arrangement. Resonance capacitors (C1, C2) are serially interconnected with a primary coil arrangement (12) and the secondary coil arrangement. The switching arrangement comprises semiconductor switches (S1-S4).    USE - Device for transferring inductive energy from a primary coil to a secondary coil of a charging device in an electric car (claimed) such as motor vehicle, plug-in car and hybrid car, for use during bad weather conditions such as rains and feel uncomfortable.    ADVANTAGE - The rectifier is laid out to rectify the alternating voltage of the secondary coil arrangement, the switching arrangements are laid out to electrically interconnect the two terminals of the secondary coil arrangement, and the primary coil and the secondary coil are formed with an air gap, thus ensuring high magnetic field strength of the secondary coil arrangement, prolonged service life, high reliability, rapid and low-loss switching effect, very spread tolerance range of a factor and high inductive energy transmission effect of the device, improving transferring efficiency, protecting charging device from short circuit of the secondary coil arrangement, avoiding secondary side error, preventing increase of primary current and reducing secondary load uncontrolled effect of the transferring device.    DETAILED DESCRIPTION - The semiconductor switches are designed as an MOSFET or an IGBT. An INDEPENDENT CLAIM is also included for a method for operating a device for transferring inductive energy from a primary coil to a secondary coil of a charging device in an electric car.
