Abstract :
This report describes an insulation-type switching power supply unit (DC/DC power converter) for mainframe computers that uses a newly developed synchronous rectifying circuit for the secondary rectification component. Compared with conventional switching power supply units, this unit offers 6% higher processing efficiency, and power output per unit volume that has been boosted by 1.75 times. As a result, this unit provides high efficiency, low voltage and high power output
