| Abstract: | Power converters which employ a high frequency (HF) link possess several attractive features such as reduced size of reactive components, fast response, and ease of commutation. Either series or parallel connection of the load to the link capacitor can be employed by such converters. Converters that have a series link capacitor-load configuration are seen by the load as a current source. A dc-dc converter which uses a parallel link capacitor-load configuration is investigated. The output dc voltage is regulated by varying the link frequency. Such a converter behaves as a voltage source and is suitable for voltage source inverter applications. The converter is analyzed. Based on the analysis, a design procedure is given. A control scheme is outlined. Results from a prototype converter are presented. |
