DC power source apparatus |
摘要 |
A DC power source apparatus converts a DC input voltage into high-frequency power by turning on/off a switching element connected to a primary winding of a transformer and converts the high-frequency power transmitted to a secondary winding of the transformer into a DC output voltage. The primary and secondary windings of the transformer include a core winding set having a primary winding P1 wound around a leg of a core defining a closed magnetic path and a secondary winding externally wound around the primary winding and another core winding set having a primary winding P2 wound around a leg of the core and a secondary winding externally wound around the primary winding. The primary winding of each of the two core winding sets has a plurality of winding layers among which a lowermost one that is closest to the core is connected to the switching element. |
