Abstract: The present invention provides a method and an apparatus for controlling the wireless induction power supply. The apparatus comprises a transmitter control circuit and a receiver control circuit. The method comprises generating a plurality of switching signals for switching a transmitter winding and generating a power; detecting a level of a transmitter signal from the transmitter winding; and controlling a switch to deliver the power from a receiver winding to a load. The receiver winding is coupled to receive the powerfrom the transmitter winding. The switching signals will be disabled if the level of the transmitter signal is not higher than a threshold over a first period or the level of the transmitter signal is higher than a high-threshold over a second period. Accordingly, the method and the apparatus according to the present invention have the foreign object detection (FOD) function for the safety.

Abstract: A regulation circuit of a power converter for cable compensation according to the present invention comprises a signal generator generating a compensation signal in accordance with a synchronous rectifying signal. An error amplifier has a reference signal for generating a feedback signal in accordance with an output voltage of the power converter. The compensation signal is coupled to program the reference signal. The feedback signal is coupled to generate a switching signal for regulating an output of the power converter. The regulation circuit of the present invention compensates the output voltage without a shunt resistor to sense the output current of the power converter for reducing power loss.

Abstract: A switching control circuit of a power converter according to the present invention comprises an input circuit and a clock generator. The input circuit is coupled to receive a feedback signal for generating a switching signal. The clock generator generates a clock signal to determine a switching frequency of the switching signal. The feedback signal is correlated to an output of the power converter. The switching signal is coupled to switch a transformer of the power converter for regulating the output of the power converter. The pulse width of the switching signal is reduced before the switching frequency of the switching signal is changed from a low frequency to a high frequency.

Abstract: A control circuit for a programmable power supply is provided. It comprises a reference generation circuit generating a voltage-reference signal and a current-reference signal for regulating an output voltage and an output current of the power supply. A feedback circuit detects the output voltage and the output current for generating a feedback signal in accordance with the voltage-reference signal and the current-reference signal. A switching controller generates a switching signal coupled to switch a transformer for generating the output voltage and the output current in accordance with the feedback signal. A micro-controller controls the reference generation circuit. The micro-controller, the reference generation circuit, and the feedback circuit are equipped in the secondary side of the transformer. The switching controller is equipped in the primary side of the transformer. The control circuit can achieve good performance for the programmable power supply.
