ABSTRACT:
Rectifying elements are connected in parallel with switching elements4-1through4-4in a switching section4for the lower voltage side and rectifying elements are connected in parallel with switching elements5-1through5-4in a switching section5for the higher voltage side. An LC resonant circuit6is provided between the winding wire3-2for the high-voltage side in the transformer3and the switching section5for the higher voltage side; currents which flows on the primary side and the secondary side is changed into a sinusoidal one; and switching is executed in the vicinity of the zero crossing points of the currents.
