The utility model discloses a
transformer subassembly and power supply with the
transformer subassembly, including framework,
magnetic core, first winding, second winding, third winding, first PCB board and second PCB board, first PCB board sets up in the bottom of framework, and second PCB board sets up in the side of framework, the first winding's head,
tail end is electrically connected on first PCB board respectively, and second winding and third winding pass the inner ring side of first winding along the axial direction, be provided with two groups of synchronous rectification circuit, two pins on second PCB board, one end of second winding is inserted in second PCB board to be connected in a pin through a group of synchronous rectification circuit, one end of third winding is inserted in second PCB board to be connected in another pin through another group of synchronous rectification circuit, and another end of second winding and third winding is downward through first PCB board through an extension support leg, and thus, effectively reduce the
welding impedance, improve
overcurrent, improve the efficiency, and modular component setting, easy to install application.
