Abstract:
1. Power converter apparatus comprising: a step-down converter circuit of switching type having an input port to couple to a supply voltage and having an output port to provide an output voltage at a magnitude that is lower than a magnitude of the supply voltage, and having a control circuit to receive a feedback signal and regulate the magnitude of the output voltage in response thereto; a DC/AC converter circuit of switching type having a primary side and a secondary side, the primary side having an input port coupled to the output port of the step-down converter circuit, the secondary side having an output port to provide an AC output voltage; a rectifier circuit having an input port and an output port, the input port being coupled to the secondary side of the DC/AC converter circuit, the output port supplying a DC voltage; and a feedback circuit to generate the feedback signal in response to the output port of the rectifier circuit.
