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.
