Discrete Time‐Domain‐Based Modelling and Control of a Resonant DC–DC Converter Suitable for Renewable Energy Systems

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper presents an in‐depth analysis of a medium voltage, high‐power resonant DC–DC converter, including the derivation and investigation of both nonlinear and linear mathematical models. We design an industrial proportional–integral controller based on these models and validate its performance through hardware‐in‐the‐loop testing, demonstrating ...
