“…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.…”

Summary In this paper, a novel non‐isolated very high step‐up DC‐DC converter is presented. The introduced converter benefits from various advantages, namely, very high voltage gain, low voltage stress on the active switch, and continuous input current with low ripple. Therefore, the presented converter is suitable for renewable energy applications. In addition, the energy of the leakage inductance of the coupled inductor is successfully recovered, and the voltage spike of the active switch is clamped during the turn‐off process. Hence, a switch with low Rds−on can be used, which decreases the conduction losses as well as cost of the converter. Furthermore, the voltage stress of the output diode is decreased, which reduces the reverse recovery problem. The steady‐state analysis and design considerations of the proposed converter are discussed. Finally, the theoretical analysis is validated with the experimental results at an output power of 150 W.

The conventional DC-DC converters have limited voltage gain at moderate duty cycles. In theory, the large duty cycles should be adopted to reach large boosting factors. But in reality, at extreme duty cycles, the effect of parasitic components become dominant, which leads to increased voltage drops on devices, increased total loss and reduced efficiency. This paper proposes a single-switch (requiring single gate-driver circuit) diode-inductor-capacitor (DLC) cell-based basic boost configuration that can solve the abovementioned issues. The employment of single-switch has led to only two operational modes (in continuous conduction mode [CCM]) and easy control strategy. The continuous input-current and large step-up capability make the proposed configuration favourable for renewable or hybrid energy systems in DC microgrids. The simple configuration, modularity, moderate blocking voltage on semiconductors, wide duty-cycle range, large voltage gains at low duty cycles, common-ground between source and load are some profits of suggested configuration. The basic topology can be expanded by addition of DLC cells. Based on comparative analysis, the proposed configuration has larger step-up capability per required components and lesser average normalized blocking voltage on semiconductors compared with other single-switch topologies. This leads to smaller and cheaper structure with fewer losses. The configuration and operational modes of proposed basic topology (and its extended version) have been explained. Then, the design considerations and small-signal modelling of basic topology have been investigated. Finally, the effectiveness and correct operation of proposed topology have been certified by comparative analysis and experimental results.
