Abstract
An asymmetrical half-bridge power converter and a method of manufacturing the same. In one embodiment, the asymmetrical half-bridge power converter includes: (1) first and second power switches configured to be controlled by complementary drive signals having nominal first and second duty cycles of D and 1-D, respectively and (2) first and second capacitors, having intrinsic capacitance values proportional to 1-D and D, respectively, and intrinsic equivalent series resistance (ESR) values proportional to D and 1-D, respectively, configured to reduce input ripple current associated with the asymmetrical half-bridge power converter.
