ABSTRACT:
A converter-controller includes a power device, coupled to the primary coil of a transformer, a resonant circuit, coupled to the primary coil and the power device, a voltage regulator, coupled to the resonant circuit, and a control logic, coupled to the voltage regulator. The converter-controller does not need a snubber circuit. Further, the transformer structure of the converter-controller does not need additional auxiliary windings around the transformer core. The described converter-controller makes it possible to use low voltage integrated circuits in high voltage applications.
