N2 - The phase-shifted full-bridge (PSFB) converter with a center-tapped rectifier (CTR) structure, commonly used in low-voltage, high-current applications, faces the issue of high voltage stress on the rectifier diodes. To address this, the center-tap clamping (CTC) circuit has been studied previously. However, applying the CTC structure increases the number of secondary windings on the transformer. In this paper, we propose a new winding technique to solve this issue. The proposed technique adds a center tap to the one-turn winding of the secondary side, instead of adding it to the two-turn winding as in the conventional CTC structure. This reduces the winding resistance, thereby decreasing conduction losses. The proposed converter was experimentally validated using a prototype designed for an output of 12V/70A and 840W.
