<p>A synchronous regulation circuit of a power converter includes a primary-side switching circuit (40) for generating switching signals and synchronous signals, an isolation device (45, 46, 47) coupled to the primary-side switching circuit (40) for transferring the synchronous signals from a primary side of a transformer (10) to a secondary side of the transformer (10), a secondary-side switching circuit (100) coupled to an output of the power converter to generate pulse signals in response to the synchronous signals and a feedback signal, and synchronous switches (51, 52). Each synchronous switch (51, 52) includes a power switch set (300, 310) and a control circuit (500). The control circuit (500) receives the pulse signals via capacitors (67, 68) for turning on/off the power switch set (300, 310). The power switch set (300, 310) is connected between the transformer (10) and the output of the power converter.</p> |
