This study presents a new flatness‐based control scheme for the quantum series–parallel LCC‐type resonant converter with output voltage doubler for high‐voltage pulse applications, like medical X‐ray imaging. Based on a previously derived continuous time model of the system, a flat output of the system model is shown. Moreover, an optimised trajectory planning algorithm with limited resonant current and the controller design are addressed. Details on the experimental set‐up and the real‐time controller implementation on an FPGA are given. Measurement results show the accuracy of the presented control method.
