Modern DC–DC resonant converters are normally built around a voltage‐source series‐resonant converter. This study aims to facilitate the practical use of current‐source parallel‐resonant converters due to their outstanding properties. To this end, this study presents a sliding‐mode control scheme, which provides the following features to the closed‐loop system: (i) high robustness to external disturbances and parameter variations and (ii) fast transient response during large and abrupt load changes. In addition, a design procedure for determining the values of the control parameters is presented. The theoretical contributions of this study are experimentally validated by selected tests on a laboratory prototype.
