“…According to this table, the efficiency of the proposed converter at full‐load is higher than the efficiency of the converters in the previous studies . The efficiency of converter in Ardi et al is higher than the proposed converter.…”

“…Efficiency comparison of the proposed converter and the other converters in the previous studies is provided in Table …”

“…The number of the components, voltage gain, and normalized voltage stress on the switch and output diode for the proposed converter and converters in the previous studies [16][17][18][19][20] are compared and provided in Table 1. Also, the voltage gain versus duty cycle for the proposed converter and converters in the previous studies [16][17][18][19][20] are plotted in Figure 5.…”

“…The number of the components, voltage gain, and normalized voltage stress on the switch and output diode for the proposed converter and converters in the previous studies [16][17][18][19][20] are compared and provided in Table 1. Also, the voltage gain versus duty cycle for the proposed converter and converters in the previous studies [16][17][18][19][20] are plotted in Figure 5. According to Figure 5 and Table 1, it can be observed that the proposed converter can provide higher voltage gain in comparison with the converters in the previous studies [16][17][18][19][20] after D = 0.22 Hence, the introduced converter is more preferred than the other topologies where the high voltage gain is required.…”

“…The coupled inductor and voltage multiplier techniques are combined in Ajami et al 14 and Axelrod et al 15 In spite of the fact that the converters in the previous studies [11][12][13][14][15] provide a high voltage gain and limit voltage spike on the switches, their input current is discontinuous with a high ripple. Therefore, in the previous studies, [16][17][18][19][20][21][22] some DC-DC converters with continuous input current and low switch voltage stress are introduced. Nevertheless, a high turn ratio and duty cycle are needed to achieve a very high step-up voltage gain in these converters.…”
