| Abstract: | A kind of drive circuit for active-clamping synchronous rectification （SR）is presented. It is suitable for high-current and high-power density applications. The drive circuit adopts gate charge retention（GCR）technology to resolve the dead time of secondary synchronous rectifiers, so reduces the loss of them and enhances the efficiency of the converter. The operation principle of the transformer secondary side is analyzed. The experiment is carried out in the active-clamping forward converter, the efficiency reaches about 89% at full load, the test result is ideal. |
