摘要： An active rectifier circuit is disclosed for providing a rectified voltage output to a point of regulation that is located downstream of the active rectifier circuit. The active rectifier circuit comprises rectifying circuitry and control circuitry operable to control the rectifying circuitry based on voltage feedback to provide a certain voltage output at the point of regulation. The control circuitry is configured to obtain voltage feedback from a first point associated with the point of regulation and to obtain parallel voltage feedback from a second, different point, and to control the rectifying circuitry based on both the voltage feedback from the first point and the voltage feedback from the second point.

摘要： A power supply includes a first power converter stage and a second power converter stage. The first power converter stage includes a first transformer winding; the second power converter stage includes a second transformer winding. The first power converter stage converts an input voltage into an intermediate voltage. The second power converter stage converts the intermediate voltage into first current contributing to generation of the output voltage. A circuit path in the power supply provides coupling of the first transformer winding in the first power converter to the second winding in the second power converter stage. Series connectivity of the first winding and the second winding provided by the circuit path creates a trans-inductance path between the first power converter stage and the second power converter stage.
