A high-density 1kW resonant power converter with a transient boost function
- General Electric Co., Schenectady, NY (United States). Corporate Research and Development
A series/parallel resonant dc-dc converter with secondary-side resonance and a novel input ``boosting`` feature is described. In order to greatly reduced the conduction loss (factor of 4) due to circulating currents in the resonant components, the boost circuit, which requires no additional active switches, operates only when needed during transient input voltage dips. This reduces the effective input voltage range over which the converter must operate and allows optimization at the steady-state input voltage. The converter employs highly efficient resonant inductors and novel z-folded thin flex circuit transformer windings in order to meet a density of greater than 50 W/in{sup 3} with an efficiency approaching 95%. The dc-dc converter was developed for use as a 270 to 50 V line converter for distributed power applications.
