Summary In DC microgrids, power converters are essential for interconnecting and controlling power flow from the renewable sources such as solar PV, wind, fuel cell, and so on with the DC grid link. A lot of DC‐DC power converters available in the literatures are used to boost the low voltage from the renewable sources to the high voltage and also to track the maximum power from these sources. To boost the output voltage, high gain converters are required. To increase the static gain of the converters, many techniques such as using voltage lift, switched capacitor, coupled inductor, and so on are used. This paper presents a novel high gain DC‐DC converter that does not use the above techniques for voltage boosting. An inductive reactive element is added in series with a switch to boost the voltage gain. This inductor is connected in parallel with the source voltage when the switches are in ON position and in series with the source when the switches are in OFF position. The proposed converter is designed to produce the output voltage of 380 V for the input of 48 V. The converter is designed to handle the power of 1 kW. With the use of the voltage boosting element, a maximum voltage gain of 28 is achieved and the efficiency of converter is about 91.9%. The performance of the proposed converter is simulated and analyzed for various conditions such as variation in input voltage, reference voltage, and load power and also for motor loads. The experimental prototype model is also built and the hardware results are shown in this paper to validate the simulation results.

A new non-isolated modified SEPIC front-end dc-dc converter for the low power system is proposed in this paper, and this converter is the next level of the traditional SEPIC converter with additional devices, such as two diodes and splitting of the output capacitor into two equal parts. The circuit topology proposed in this paper is formulated by combining the boost structure with the traditional SEPIC converter. Therefore, the proposed converter has the benefit of the SEPIC converter, such as continuous input current. The proposed circuit structure also improves the features, such as high voltage gain and high conversion efficiency. The converter comprises one MOSFET switch, one coupled inductor, three diodes, and two capacitors, including the output capacitor. The converter effectively recovers the leakage energy of the coupled inductor through the passive clamp circuit. The operation of the proposed converter is explained in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The required voltage gain of the converter can be acquired by adjusting the coupled inductor turn’s ratio along with the additional devices at less duty cycle of the switch. The simulation of the proposed converter under CCM is carried out, and an experimental prototype of 100 W, 25 V/200 V is made, and the experimental outcomes are presented to validate the theoretical discussions of the proposed converter. The operating performance of the proposed converter is compared with the converters discussed in the literature. The proposed converter can be extended by connecting voltage multiplier (VM) cell circuits to get the ultra-high voltage gain.
