Gate drive circuit for synchronous rectification

Abstract

Systems, methods and apparatus are disclosed for AC to DC conversion. In one aspect a rectifier circuit for providing DC voltage to a load based at least in part on an AC input from an AC output source having a first and second terminal is provided. The rectifier circuit includes a first transistor and a second transistor, each transistor having a first terminal, a second terminal, and a control terminal. The second transistor is configured to limit a voltage applied to the control terminal of the first transistor. The control terminal of the second transistor is coupled to a voltage source applying a control voltage to the control terminal. The control terminal of the first transistor is coupled to the first terminal of the second transistor. The first and second transistors have their second terminals respectively connected to the second and first terminals of the AC output source.
