COMPARISON

Comparing performance between the proposed converter and relevant converters is provided in Table 1. Fig. 5 (a) and (b) show the comparison results under n =1 with voltage gain in both step-up and step-down modes, respectively. Fig. 6 (a) and (b) give voltage stress on power switch, and current stress on power switch, respectively.
In step-up mode, the proposed converter has higher voltage gain than converter in Banaei and Ajdar Faeghi Bonab14, Sarikhani, et al.24 , and Wang, et al.27. In step-down mode, converters in Banaei and Ajdar Faeghi Bonab14, Dhimish and Schofield15, Kumar and Krishnasamy17, and Hosseinpour, et al.30 of voltage gain are less than proposed converter. Although the voltage gain in Alizadeh, et al.21 is equal to the proposed converter, the current stress of power switch in this converter is considerably larger than the proposed converter. In the operating condition of experiment, the voltage stress of power switch has the superior performance comparing with the relevant converters except for the power switchS 2 of the converter in Wang, et al.27. Additionally, the current stresses of power switches S 1 and S 2 in Wang, et al.27 are higher than the current stresses ofS 1 and S 2 in the proposed converter, respectively. Moreover, the proposed converter has lower number of inductors and higher frequency than relevant converters to decrease the volume of the converter.
