“…Nonetheless, due to voltage gain limitations, it cannot be utilized for high voltage applications [6,7]. In fact, to boosting of the voltage gain, the power switch's duty cycle should be set to a high value [8]. As a result, there is a significant conduction loss and a low power efficiency.…”

In this paper a new topology of non‐isolated high step‐up DC‐DC is proposed for renewable applications like photovoltaic (PV) power generation. This converter is designed based on coupled inductor and VMC techniques. The main benefits of the presented topology are: (1) Continues input current with low ripple, (2) low voltage stress across semiconductors, (3) soft switching of diodes (ZVS and ZCS), (4) high voltage gain with low duty cycle, (5) low volume and cost, and (6) high power efficiency. To obtain a high output voltage, the secondary side of the coupled inductor is integrated with VMC, resulting in a large voltage gain with low duty cycles and reduced conduction loss of power switches. Additionally, diodes' zero voltage switching (ZVS) and zero current switching (ZCS) improve the efficiency of the proposed converter. The used VMCs act as a voltage clamp, and the peak voltages across power switches are reduced. The presented converter's operational modes, steady‐state, and efficiency analysis are discussed. Additionally, to indicate the performance of the suggested structure, a 200 W prototype with Vin = 33 V and Vo = 403 V voltage conversion is built, and the experimental results are presented. The experimental efficiency at Po = 200 W is measured 95.29%. Also, efficiency is measured more than 95 % for Po = 20 W to 200 W.

In this paper, an interleaved DC–DC converter with high voltage gain capability is presented. The proposed converter is synthesized from a coupled-inductor (CI) based interleaved boost converter (IBC). For enhancing the voltage gain capability, voltage-lift capacitor, and diode-capacitor multiplier (DCM) cells are employed at the primary and secondary sides of the CIs. The proposed hybrid gain extension concept is practically validated using simulation and experimentation. A 185W prototype version of the proposed converter is switched at 50 kHz under laboratory conditions from a 18 V input to realize 380 V at the output port. The switches in the proposed converter operate at 0.5 duty ratio and experience a very low voltage stress of only 10.5% of the output voltage. Moreover, due to the interleaving mechanism, the input current ripple is just 11% of the total input current and the current rating of the switches is halved. Due to the adopted gain extension mechanism, the voltage stress on almost all the diodes is also significantly reduced. The swift dynamic response of the converter under closed-loop conditions is also practically demonstrated. Further, the beneficial features of the proposed converter are clearly validated by benchmarking its parameters with many state-of-the art converters which are available in literature.
