摘要： An inductive power receiver including a receiving coil, first capacitor and power conditioning circuitry for providing power to a load. The inductive power receiver also includes a variable capacitance and/or a variable inductance connected in parallel with at least one of the receiving coil and the first capacitor. The variable capacitance includes a variable impedance and a second capacitor having a capacitance at least twice the capacitance of the first capacitor. The variable inductance includes a variable impedance and an inductor having an inductance at least twice the inductance of the receiving coil. A control circuit controls the variable impedance based on a load voltage input and a reference voltage input so as to regulate the power provided to the load.

摘要： An overcurrent protection circuit for use in a power supply system to control switching on of the circuit. The circuit is connected between a voltage source and a load. A current sensing resistor senses the current flowing to the load and a pair of thermally coupled transistor switches detect a predetermined voltage drop across the current sensing resistor when the current in the current sensing resistor exceeds a first threshold. A control switch limits the power delivered to the load from the voltage source when the pair of transistor switches detecting the predetermined voltage drop.
