“…In this section, a comparative study of the proposed converter with other similar high gain converter structures is presented, such as the multilevel boost converter [26], non-isolated DC-DC boost converter with voltage-lift technique [18], Traditional switched inductor based DC-DC boost converter [21], converter-I in [22], modified SEPIC converter in [23], ASL-SU2C-VO-configuration [24], and modified SEPIC converter (MSC) [25]. The number of components, normalized voltage stress across the switches, switch current stress, efficiency at rated power, and the gain in voltage for these converters are presented in Table I.…”

“…However, the switched-inductor/capacitor stages incorporated in these converter configurations increase the voltage stress across the switches, the components count, cost, and complexity of the circuit. Furthermore, the switch voltage stress in the switchedinductor boost converter is relatively high with a limited value of gain, and in quadratic converters switch voltage stress value is the same as output voltage [18]. On the other hand, in the cascade boost converter, even though the two switches can be combined to make one switch to reduce circuit complexity, the voltage and current stress across the switch are still high [19].…”

This paper deals with an active switched inductor network-based high gain boost converter.By using less number of components in circuit topology, a higher gain in voltage can be attained at a small duty cycle value by using the proposed converter, which helps in reducing the switch voltage stress and conduction loss. In addition, it draws continuous input current, has lower diode voltage stress, and lower passive component voltage ratings. The operating principles and key waveforms in Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) are presented. Parameter design, power loss calculation, characteristics, and comparative study with other non-isolated converters have been presented. Finally, a 200W hardware prototype is constructed and the viability of the proposed converter is verified through the experimentally obtained results.

“…From Equation (14), the expression for the magnetizing inductance is derived and presented in Equation (16). This is the minimum value of the magnetizing inductance (L m ) to maintain the converter operation in CCM, and the converter goes to DCM operation if the value of L m is small.…”

“…This technique also helps to achieve a high conversion efficiency due to the lower part count. Due to various merits, the conventional SEPIC converter is provided with the coupled inductor to increase the voltage gain [14][15][16][17][18]. However, the converters with the coupled inductor have problems such as two magnetic circuits with a few extra components which are used to increase the voltage gain, but which may damage the power density of the converters [19][20][21], and the necessity of clamp circuits to recover the energy leaked by the coupled inductor which further increases the losses in the converter [22].…”

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.

Here, a new family of non-isolated step-up/down and step-up switched-capacitor (SC)-based DC-DC converters are proposed possessing many advantages as lower voltage stress on capacitors and higher voltage gain compared to previously introduced DC-DC converters. The proposed converter structures have multiple capacitors which are based on principles of DC-DC SC converters. Therefore, the amount of power transfer from the input to the output is higher in the proposed converters. Generally, the proposed converters are more suitable for industrial applications, especially for generating highvoltage gains in lower duty-cycles. For proving the analysis, comprehensive comparisons and precise experiments have been performed which show remarkable performance of the proposed converter topologies.
