SYNCHRONOUS RECTIFIER, USE OF SUCH A SYNCHRONOUS RECTIFIER IN A SWITCHED-MODE POWER SUPPLY, AND SWITCH MODE POWER SUPPLY

摘要

The invention relates to a synchronous rectifier (1), which rectifies an alternating voltage signal as an input signal and/or forwards a direct voltage signal as an input signal for use as an output signal, comprising at least: a rectification unit (5) consisting of at least one controllable switching element (12); a smoothing unit (7), which is connected downstream of the rectification unit (5) and smoothens the signal rectified or forwarded by the rectification unit (5) and provides said signal for use as an output signal (Ua); a control logic system (2, 3, 4), which actuates the rectification unit (5) using the input signal and the output signal (Ua) coming from the smoothing unit (7).
