Patent ID: 6930895

Claim:
A computer power supply wherein a first switching element and a second switching element operating with a DC voltage as an input are disposed on the primary side of a high-frequency transformer, said first switching element is connected to one end of a primary side winding of said high-frequency transformer, and said second switching element is connected to the same end of the primary side winding as the connection side of said first switching element via a resonance condenser and in a state of differing polarity to said first switching element, said primary side winding, resonance condenser, and two switching elements constituting a partial resonance circuit, a secondary side output circuit for driving a load is connected to the secondary side of said high-frequency transformer via a winding, a first driving circuit and a second driving circuit having a delay element are provided for driving and halting said first switching element and second switching element on the basis of a driving signal by causing the respective phases thereof to differ, and a reverse converter is provided for supplying to the input portion of one of said driving circuits insulation from the other of said driving circuits and a reverse input voltage.
