This study presents a novel dead‐time elimination method for operating nine‐switch converter. The proposed method assumes the unique switching cells of nine‐switch converter to operate under several subintervals divided during a fundamental period. Owing to the unidirectional conduction characteristics of switching cells, the nine‐switch converter can operate without dead‐time protection. Besides, for a special subinterval during which none of switching cells can be adopted, a novel switching signal transformation method is proposed to fully eliminate the dead‐time protection during the operation of nine‐switch converter. Matlab simulations and experimental results verify the effectiveness of proposed modulation scheme.
