Abstract

See full text

A switched-mode power converter includes timing control feedback loop circuits to minimize or eliminate the potential difference across a high-power switch and a low-power switch during their transitions times. A first feedback circuit compares the measured voltage across the high-power switch at the moment the high-power switch closes with the input voltage to the high-power switch to control a low-to-high delay time. A second feedback circuit compares the measured voltage across the low-power switch at the moment the low-power switch closes with the input voltage to the low-power switch to control a high-to-low delay time. A third feedback circuit compares the measured voltage across the low-power switch at the moment the low-power switch opens. The output of the third feedback circuit is provided as inputs to the first and second feedback circuits. The third feedback circuit also controls the frequency of the power converter.
