Resonant power converter with current sharing among multiple transformers |
摘要 |
A resonant power converter has a plurality of transformers, each having a primary winding and a secondary winding coupled thereto; the primary windings of all of the plurality of transformers are connected in series. The plurality of transformer secondary circuits are effectively connected in parallel, for current addition. a relatively small portion of the resonance capacitor is placed across each primary winding to insure a low impedance which causes the secondary-winding-connected rectifiers to commutatively switch substantially independently and share the entire output current substantially equally. A plurality of lower power transformers are thus utilized to replace a single high power transformer, so that leakage inductance is reduced and a higher operating frequency can be maintained.
