Inhalt:
A dc-dc converter has been proposed in order to obtain ultra-efficient (nominal efficiency 99.5%), ultra-compact (50kW/dm3) dc-dc- converter where the input voltage is changed in a very wide range (between 300V and 1000V). Due to the very wide range of the input voltage, the proposed converter is implemented as a combination of a series resonant converter and an ordinary PWM converter. The resonant capacitor is one of the most important parts of the system due to high effective current that it has to conduct. This paper presents experimental results obtained during the selection of the most adequate capacitor technology for the resonant capacitor.
