| 摘要 |
The circuit has a self-controlled synchronous rectification main circuit receiving secondary voltage of a secondary unit (10B) of an intermediate tapped transformer (10) comprising a secondary winding (10Ba) that is mounted in series with another secondary winding (10Bb). The transformer delivers simple alternation regulation voltage (V2). A synchronous rectification auxiliary circuit is controlled by a post-synchronous regulation control circuit (26) to receive the regulation voltage and deliver another simple alternation regulation voltage (V3) for producing an auxiliary output (Va). |
