摘要：
This paper presents a novel dead-time elimination method for operating nine-switch converter. The proposed method assumes unique switching cells of nine-switch converter to operate under several subintervals during a fundamental period. Due to the unidirectional conduction characteristics of switching cell, the nine-switch converter can operate without dead-time protection. For a special subinterval during which none of switching cells can be adopted, a novel and simple switching signal transformation method is proposed to fully eliminate dead-time in nine-switch converter. Matlab simulations verify the effectiveness of proposed modulation scheme.
