ABSTRACT:
A small-sized, highly efficient power conversion apparatus is provided which is capable of stabilizing its output and which can be easily applied to parallel driving. The power conversion apparatus turns on and off paired switching elements, lets an alternating current flow through a primary winding of a transformer, rectifies and smoothes an AC voltage thus induced across a secondary winding, thereby obtaining a DC output. On the basis of a rectangular wave signal having a duty ratio of 50% formed by a rectangular wave oscillator means, a dead time generator generates complementary on/off control signals having a dead time and supplies the on/off control signals to the paired switching elements.
