This paper proposes a generalized scheme of new softswitching interleaved boost converters that is suitable for high step-up and

high-power applications. The proposed converter is configured with proper numbers of series and parallel connected basic cells in

order to fulfill the required output voltage and power levels, respectively. This leads to flexibility in device selection resulting in high

component availability and easy thermal distribution. Design examples of determining the optimum circuit configuration for given

output voltage and power level are presented. Experimental results from a 1.5-kW prototype are provided to validate the proposed

concept.
