摘要：In this paper a new step-up DC-to-DC converter with high voltage conversion ratio with small voltage stress is presented. The converter is suitable for the applications where high voltage conversion ratio is required. The proposed converter is different from the conventional Cuk converter and for a given duty ratio provides high conversion ratio with reduced switch voltage stress. Due to low switch voltage stress, the hybrid switch converter utilizes a MOSFET switch with low voltage rating and low on resistance. Hence it has low conduction loss and high efficiency. The principles of operation and the theoretical analysis are presented in this paper. In order to validate the theoretical results the proposed converter is simulated for 35 W prototype operating at 100 KHz
