ABSTRACT:
A power converter provides power to a phased-array radar antenna system. The converter adjusts its internal zero-voltage switching current so that it efficiently provides a clean power signal over a wide range of potential loads. More specifically, the zero-voltage switching current is increased in response to a decrease in load. The zero-voltage switching current in the converter can be maintained based on use of the same control signals that are otherwise used to regulate (via switching) the voltage output of the converter.
