Abstract
A synchronous bridge rectifier comprises a plurality of synchronously switched elements and a plurality of controller circuits, one for each of the synchronously switched elements. The synchronously switched elements may be field-effect transistors. Each controller circuit is configured to sense voltage across the corresponding synchronously switched element to control opening and closing of the synchronously switched element so as to rectify the alternating current input signal to form a direct current output signal.
