Series Resonant Converter for DC fast-charging electric vehicles with wide output voltage range

The paper presents an investigation of the operating range achievable with a series resonant converter. In its fully resonant mode, the series resonant converter is an attractive topology due to the switching at zero current, which results in high efficiency. The question that is addressed by this paper is if the topology is applicable for fast DC charging of electric vehicles, that is if it can cover the required operating range and what effective efficiency is achieved over this operating range.
