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.

The automobile companies are focusing on recent technologies such as growing Hydrogen (H2) and Fuel Cell (FC) Vehicular Power Train (VPT) to improve the Tank-To-Wheel (TTW) efficiency. Benefits, the lower cost, 'Eco' friendly, zero-emission and high-power capacity, etc. In the power train of fuel cell vehicles, the DC-DC power converters play a vital role to boost the fuel cell stack voltage. Hence, satisfy the demand of the motor and transmission in the vehicles. Several DC-DC converter topologies have proposed for various vehicular applications like fuel cell, battery, and renewable energy fed hybrid vehicles etc. Most cases, the DC-DC power converters are viable and cost-effective solutions for FC-VPT with reduced size and increased efficiency. This article describes the state-of-the-art in unidirectional nonisolated DC-DC Multistage Power Converter (MPC) topologies for FC-VPT application. The paper presented the comprehensive review, comparison of different topologies and stated the suitability for different vehicular applications. This article also discusses the DC-DC MPC applications more specific to the power train of a small vehicle to large vehicles (bus, trucks etc.). Further, the advantages and disadvantages pointed out with the prominent features for converters. Finally, the classification of the DC-DC converters, its challenges, and applications for FC technology is presented in the review article as stateof-the-art in research.

“…This topology has many advantageous features such as high frequency operation capability, low input/output current ripple, low ON‐state voltage drops, and bidirectional power flow management. Other possibilities include converters that use the voltage multiplier cells in which the voltage gain is extended, and the switch voltage stress is reduced by the winding‐cross‐coupled inductors (WCCIs) and the voltage multiplier cells, switched capacitors, and coupled inductors for their demanded voltage boosting . These converters can provide higher voltage gains than the conventional DC‐DC boost converter but at the expense of more components, especially switches and their associated driving circuitries.…”

Summary In this paper, a new structure for a DC‐DC boost converter is proposed. The presented converter provides a high voltage transfer gain with lower duty cycle. Low current and low voltage stress on the switch, enlarged area of operating in continuous conduction mode (CCM), reduced size of the inductors, and the input filter are the main advantages of the proposed converter. The high voltage transfer gain with low number of elements has made it suitable to implement. Hence, using only one switch has made the control of the proposed converter easy. Besides, decreased switching losses and higher efficiency are obtained. The proposed structure is a combination of the Luo converter and a booster unit, which its analysis is studied in three modes, CCM, boundary conduction mode (BCM), and discontinuous conduction mode (DCM). Furthermore, in order to validate the analysis and feasibility of the proposed converter, the experimental results are developed on a low power prototype.
