“…In addition to these soft-switching circuits, some nonisolated and isolated dc-dc converters also benefit from implementing a small resonant capacitor in series with one side of the magnetic coupling (i.e., coupled inductor/transformer) in order to achieve quasi-resonant operation. These circuits often have stable soft-switching features throughout their operating points and load variations [130], [203], [204], [207], [210], [266].…”

“…Softswitching current-fed converters such as dual inductor-fed and full-bridge converters are another common solution for many high step-up applications [267]- [268]. b) Built-in transformers: The use of built-in transformer (also known as the transformer-assisted concept) is another approach for using magnetic elements in high step-up dc-dc converters [130], [205]- [211]. This concept is derived from the idea of deriving nonisolated circuits from isolated circuits using direct energy transfer.…”

DC-DC converters with voltage boost capability are widely used in a large number of power conversion applications, from fraction-of-volt to tens of thousands of volts at power levels from milliwatts to megawatts. The literature has reported on various voltage-boosting techniques, in which fundamental energy storing elements (inductors and capacitors) and/or transformers in conjunction with switch(es) and diode(s) are utilized in the circuit. These techniques include switched capacitor (charge pump), voltage multiplier, switched inductor/voltage lift, magnetic coupling, and multistage/-level, and each has its own merits and demerits depending on application, in terms of cost, complexity, power density, reliability, and efficiency. To meet the growing demand for such applications, new power converter topologies that use the above voltage-boosting techniques, as well as some active and passive components, are continuously being proposed. The permutations and combinations of the various voltage-boosting techniques with additional components in a circuit allow for numerous new topologies and configurations, which are often confusing and difficult to follow. Therefore, to present a clear picture on the general law and framework of the development of next-generation step-up dc-dc converters, this paper aims to comprehensively review and classify various step-up dc-dc converters based on their characteristics and voltage-boosting techniques. In addition, the advantages and disadvantages of these voltage-boosting techniques and associated converters are discussed in detail. Finally, broad applications of dc-dc converters are presented and summarized with comparative study of different voltage-boosting techniques.

“…Coupled inductors are precious components of non-isolated converter, which firstly store the energy in one part and then in other cycle power the load. Various application do not desire for isolation because, coupled inductor is enough to provide auxiliary and profitable boosting techniques in converter instead of isolation [16][17]. Switched Capacitor SC (switched capacitor) is general and efficient way of voltage boost techniques, which is applied in numerous applications.…”

Boost dc-dc converters are employed to uplifting the level of voltage from input to a higher output level. This paper presents a review on voltage boosting techniques and their application for step-up dc-dc converter. These boosting techniques comprise switched capacitor, voltage multiplier, multistage, magnetic coupling and switched inductor (voltage lifting). All of these techniques consider demerits and merits depending on applications in term of efficiency, reliability, cost, power density and complexity. Due to many difficult topologies and additional components, these techniques can not to define frame work of boost dc-dc converter. Therefore, boost dc-dc converter present clear picture to clarify several techniques of boosting up the voltage.

The switched‐inductor‐based voltage lift converters offer high voltage gain. However, their input current has step changes due to switched‐inductor configuration and is peaky due to the voltage lift capacitor charging current. This article proposes a new high‐gain DC‐DC converter where an additional boost converter cell is incorporated in a conventional voltage lift boost converter to charge the voltage lift capacitor with a constant current, avoiding a peaky charging current from the supply. The operating principle of the proposed converter demands phase‐shifted switching signals to achieve high voltage gain and reduce ripple in the input current. High‐gain, continuous input current, positive output voltage, common ground between input and output ports, and low voltage stress on active switches are the major characteristics of the proposed converter. The operating principle, steady‐state analysis, and control design have been discussed in detail. A 200 W, 30 V/300 V, and 50 kHz laboratory prototype is developed to validate the operation of the proposed converter.
