<P>PROBLEM TO BE SOLVED: To downsize of a power transformer and power conversion equipment using the same. <P>SOLUTION: To solve the above problem, this power transformer has a primary winding to which a predetermined voltage is applied, a secondary winding in which a converted voltage is generated according to the voltage applied to the primary winding, a winding shaft over which the primary winding and secondary winding are wound, and an insulating member which is provided at the peripheral wall of the winding shaft. The secondary winding is wound separately around the winding shaft at least two points in the axial direction of the winding shaft across the insulating member. <P>COPYRIGHT: (C)2010,JPO&INPIT |
