1. a kind of contactless power receiver being suitable for inductively power transmission system, including:

  • A. pick-up loop;

    B. the semiconductor switch being connected in series with the capacitor or inductor for being tuned to power receiver;

    AndC. control circuit, the control circuit are existed at least part of the opereating specification of semiconductor switch with semiconductor switchThe linear model for disconnecting and connecting switching at runtime between ohmic region drives the grid of the semiconductor switch, to be based on described non-connectThe output for touching power receiver is tuned the power receiver,Wherein, the control circuit includes operational amplifier, the operational amplifier be configured to by reference voltage with it is described non-The output of contact power receiver is compared, and driving voltage is provided with the grid at least one semiconductor switch, thus withThe linear model drives at least one semiconductor switch, to be provided based on the output of the contactless power receiverControl to the power receiver.
