MAGNETIC INTEGRATION DOUBLE-ENDED CONVERTER |
摘要 |
<p>A magnetic integration double-ended converter with an integrated function of a transformer and an inductor includes: an integrated magnetic member having a magnetic core with three magnetic columns, including at least three windings (N P , N S1 , N S2 ) and at least one energy storage air gap, where a primary winding (N P ) and a first secondary winding (N S1 ) are both wound around a first magnetic column or are both wound around a second magnetic column and a third magnetic column, and a second secondary winding (N S2 ) is wound around the second magnetic column and a total output current flows through the second secondary winding (N S2 ); an inverter circuit with double ends symmetrically working, acting on the primary winding (N P ); and a group of synchronous rectifiers (SR 1 , SR 2 ), gate electrode driving signals of which and gate electrode driving signals of a group of power switch diodes (S 1 , S 2 ) of the inverter circuit with the double ends symmetrically working complement each other. The magnetic integration double-ended converter can reduce a loss of the windings and a leakage inductance of a primary side and a secondary side, thereby implementing high efficient conversion of energy.</p> |
