  • Patent number: 11496042
    Abstract: The invention relates to a method and to a device for operating a bidirectional voltage transformer connectable to a primary battery and having a primary-side smoothing capacitor, an inductive transformer, and a secondary-side clamping capacitor, wherein, before the primary battery is connected, a voltage at the primary-side smoothing capacitor is matched to a voltage of the primary battery by a cyclical transfer of charge from the secondary-side clamping capacitor. The voltage of the primary-side smoothing capacitor is matchable in this way to the voltage of the primary battery before the primary battery is connected, and current spikes thus avoided during connection of the primary battery.

  • Patent number: 11495995
    Abstract: A wireless power receiving circuit includes a transistor based rectifier receiving an AC input voltage, and control logic receiving an overvoltage signal. The control logic generates control signals for controlling turn on of transistors within the transistor based rectifier based upon the overvoltage signal so as to cause the transistor based rectifier to produce a rectified output voltage from the AC input voltage. A comparator compares the rectified output voltage to a reference voltage and asserts the overvoltage signal if the rectified output voltage is greater than the reference voltage. In response to assertion of the overvoltage signal, the control logic asserts the control signals to simultaneously turn on all transistors of the transistor based rectifier.
