A full bridge phase shifted power supply with synchronous rectification and current doubler and method for dynamically adjusting delay parameters thereof mainly have multiple delay parameter combinations respectively varying with multiple loads and embedded in a controller of the power supply. The delay parameter combinations serve to determine driving waveforms of two rectification switches of a synchronous rectification and current doubler circuit of the power supply. When the load of the power supply varies, the controller dynamically performs a corresponding delay parameter combination so as to vary the driving waveforms of the rectification switches of the synchronous rectification and current doubler circuit and enhance the operating efficiency of the power supply.

Dynamically adjusting drive signals for full bridge phase shifted converter and current doubler synchronous rectifier

A connection-sensing DC plug has an insulative body, a connection portion, two power terminals, a conductive sheet and a retractable pin. The connecting portion is adapted to electronically connect to a target device and has an isolation layer and a ground layer. The conductive sheet is mounted in the insulative body and contacts either the isolation layer or the ground layer. The retractable pin is movably mounted in the insulative housing parallel to the connecting portion, with one end securely engaging the conductive sheet and the other end protruding from the insulative body. When the DC plug is connected to the target device, the retractable pin is pressed and moves inward to bend the conductive sheet, turning the conductive sheet to a floating state and resulting in a trigger signal.
