摘要： A power converter for converting input power to output power includes a first transformer circuit, a second transformer circuit, and balance circuitry. The first transformer circuit includes a first primary winding for receiving a first part of the input power and a first secondary winding for generating a first part of the output power. The second transformer circuit includes a second primary winding for receiving a second part of the input power and a second secondary winding for generating a second part of the output power. The balance circuitry is coupled to a first terminal of the first secondary winding and a second terminal of the second secondary winding, and operable for balancing the first and second parts of the output power by passing a signal between the first and second terminals. The first and second terminals have the same polarity.

摘要： A controller for a DC/DC converter controls a first, second, third, and fourth switches according to pulse signals generated alternately. The controller turns off the third switch on detection of a first edge of a first pulse signal, turns on the first switch after a delay from the detection of the first edge, turns off the fourth switch on detection of a second edge of the first pulse signal, turns on the second switch after a delay from the detection of the second edge, turns off the first switch on detection of a third edge of a second pulse signal, turns on the third switch after a delay from the detection of the third edge, turns off the second switch on detection of a fourth edge of the second pulse signal, and turns on the fourth switch after a delay from the detection of the fourth edge.
