PHASE-SHIFT FULL BRIDGE CONVERTER

原文（中国語）

A phase shift full bridge (PSFB) converter includes: a transformer having primary and secondary sides; a first pair of switch devices connected in series at a first node coupled to a first terminal of the primary side; a second pair of switch devices connected in series at a second node coupled to a second terminal of the primary side; diode devices connected in series at a third node coupled to the first terminal; an inductor coupled between the first and third nodes; a secondary-side rectifier; and a controller. In one mode, the controller operates the second pair of switch devices as a leading power transfer leg and the first pair of switch devices as a lagging power transfer leg. In another mode, the controller operates the first pair of switch devices as the leading power transfer leg and the second pair of switch devices as the lagging power transfer leg.
