Abstract
Systems for power conversion, and controllers and methods for operating a power converter. The method includes receiving high-side and low-side primary signals that drive primary transistors of a power converter. The method also includes receiving a combined drain voltage signal for high-side and low-side synchronous rectifier (SR) transistors of the power converter. The method further includes generating a high-side SR signal based on the low-side primary signal and generating a low-side SR signal based on the high-side primary signal. The method also includes determining high-side and low-side body diode conduction times based on the combined drain voltage signal. The method further includes adjusting the high-side SR signal based on the high-side body diode conduction time and adjusting the low-side SR signal based on the low-side body diode conduction time.
