<p>PROBLEM TO BE SOLVED: To reduce a power loss in a composite resonant switching converter, to assure a stabilized ZVS under heavy load conditions, and to improve a manufacturing efficiency. SOLUTION: A primary winding and a secondary winding of an insulating converter transformer of a switching power source circuit as a composite resonance type are so-called reversely wound, and connected in an additive polarity. Since a primary magnetic flux cancels a secondary magnetic flux to each other in this structure, no saturation occurs even without executing a gap to a core of the transformer.</p> |
