摘要： A synchronous rectifier circuit rectifies an AC input voltage to produce a DC output voltage. The synchronous rectifier circuit comprises MOSFET switches coupled within the secondary transformer windings resulting in a shortened AC current path compared to conventional synchronous rectifier circuits. The shortened current path migrates skin and proximity effects, substantially improving the power efficiency of the synchronous rectifier circuit. A rectifier assembly integrates one or more synchronous rectifier circuit within a magnetic core.

摘要： A controller, power converter, and a related method for secondary side control of a switch are disclosed herein. An embodiment of the present invention includes a controller. The controller comprises a drain to source voltage (VDS voltage) input configured to receive the VDS voltage of a transistor, a gate drive output configured to output a gate drive voltage to a gate of the transistor, and control logic configured to initiate a minimum on time signal independent of triggering the gate drive voltage to activate the transistor. A related method comprises comparing a VDS voltage of a transistor to a plurality of voltage threshold levels, driving a gate of the transistor when the VDS voltage crosses a predetermined voltage threshold, and asserting a minimum on time signal when the VDS voltage crosses another predetermined voltage threshold independent of driving the gate of the transistor.
