ABSTRACT:
An object of the present invention is to provide a computer power supply in which, by improving the circuit itself, internal heat loss can be reduced, thereby greatly improving efficiency. A partial resonance circuit8is constituted by a primary side winding N1of a high frequency transformer3, a resonance condenser7, and two switching elements Q1, Q2, a secondary side output circuit4for driving a load is connected to a secondary side of the high frequency transformer3via a winding, and a reverse converter11for driving and halting the first switching element and second switching element by causing the respective phases thereof to differ on the basis of a driving signal is provided.
