The interleaving technique is a well‐known technique applied in high power applications to share the output power between two modules while decreasing the input current and output current ripple. Moreover, zero current switching technique can be used in order to reduce the switching losses and increase the power density. Zero‐current‐switching (ZCS) condition as the soft‐switching technique is usually applied for IGBT switches in order to eliminate tailing current losses. In this study, a new ZCS pulse‐width‐modulation (ZCS‐PWM) interleaved boost converter is proposed which applies only one auxiliary switch. In the proposed converter ZCS condition is provided for main switches while the auxiliary switch is also soft switched. The principle of operation, performance analysis, and design method of the proposed converter are presented in details. Finally, the theoretical results are verified by experimental results.
