Controller for a Power Converter
First Claim
1. A controller employable with a bridge rectifier having first and second synchronous rectifier switches, comprising:
- an amplifier configured to enable a turn-on delay for said first synchronous rectifier switch; and
a discharge switch having first and second switched terminals coupled to gate and source terminals, respectively, of said first synchronous rectifier switch and configured to discharge a gate-to-source capacitance of said first synchronous rectifier switch to enable a turn off thereof.

Abstract
A controller for a power converter and method of operating the same employable with a bridge rectifier having first and second synchronous rectifier switches. In one embodiment, the controller includes an amplifier configured to enable a turn-on delay for the first synchronous rectifier switch SR. The controller also includes a discharge switch Q3 having first and second switched terminals coupled to gate and source terminals, respectively, of the first synchronous rectifier switch SR and configured to discharge a gate-to-source capacitance of the first synchronous rectifier switch SR to enable a turn off thereof.
