TL;DR: A high voltage gain Switched Capacitor Boost Converter is designed for fuel cell electric vehicle (FCEV) applications and an adaptive neuro-fuzzy inference system (ANFIS) based MPPT technique is adopted for the fuel cell system for extracting the maximum power at different temperature conditions.
Abstract: Designing of a high voltage gain or high step-up boost converter is the major challenge in the high power applications. In this work, a high voltage gain Switched Capacitor Boost Converter (SCBC) is designed for fuel cell electric vehicle (FCEV) applications. The designed converter achieves the high voltage gain with low duty cycle and reduces the voltage stress across the power semiconductor switches. The converter output voltage is given to the Brushless DC (BLDC) motor through a DC link and a Voltage Source Inverter (VSI) for the propulsion of the vehicle. An adaptive neuro-fuzzy inference system (ANFIS) based MPPT technique is adopted for the fuel cell system for extracting the maximum power at different temperature conditions. The performance analysis of fuel cell electric vehicle system with SCBC is done by using the MATLAB/Simulink environment.

Abstract: Globally, the research on electric vehicles (EVs) has become increasingly popular due to their capacity to reduce carbon emissions and global warming impacts. The effectiveness of EVs depends on appropriate functionality and management of battery energy storage. Nevertheless, the battery energy storage in EVs provides an unregulated, unstable power supply and has significant voltage drops. To address these concerns, power electronics converter technology in EVs is necessary to achieve a stable and reliable power transmission. Although various EV converters provide significant contributions, they have limitations with regard to high components, high switching loss, high current stress, computational complexity, and slow dynamic response. Thus, this paper presents the emerging trends in analytical assessment of power electronics converter technology incorporated energy storage management in EVs. Hundreds (100) of the most significant and highly prominent articles on power converters for EVs are studied and investigated, employing the Scopus database under predetermined factors to explore the emerging trends. The results reveal that 57% of articles emphasize modeling, experimental work, and performance evaluation. In comparison, 13% of papers are based on problem formulation and simulation analysis, and 8% of articles are survey, case studies, and review-based. Besides, four countries, including China, India, the United States, and Canada, are dominant to publish the maximum articles, indicating 33, 17, 14, and 13, respectively. This review adopts the analytical assessment that outlines various power converters, energy storage, controller, optimization, energy efficiency, energy management, and energy transfer, emphasizing various schemes, key contributions, and research gaps. Besides, this paper discusses the drawbacks and issues of the various power converters and highlights future research opportunities to address the existing limitations. This analytical assessment could be useful to EV engineers and automobile companies towards the development of advanced energy storage management interfacing power electronics for sustainable EV applications.

TL;DR: In this article, a switched-capacitor-based dual-switch dc-dc converter with a high-boost voltage gain is proposed, which can obtain a highvoltage gain with a small duty cycle, which decreases the voltage stress and the conduction loss on the power switches.
Abstract: A switched-capacitor-based dual-switch dc–dc converter with a high-boost voltage gain is proposed in this paper. The proposed converter can obtain a high-voltage gain with a small duty cycle, which decreases the voltage stress and the conduction loss on the power switches. This paper presents the key waveforms, the operating principles at the continuous conduction mode and the discontinuous conduction mode, and the parameter design. Moreover, a comparison between the proposed converter and other nonisolated converters has been completed. To verify the operating principle, a 200 W prototype is constructed with an input voltage of 25–50 V and an output voltage of 200 V. The simulation and experimental results are shown.

TL;DR: The proposed neural network MPPT controller uses a radial basis function network (RBFN) algorithm for tracking the maximum power point of the PEMFC, supplying electric vehicle powertrain through a high voltage-gain dc–dc boost converter.
Abstract: Due to the more vigorous regulations on carbon gas emissions and fuel economy, Fuel cell electric vehicles (FCEV) are becoming more popular in the automobile industry. This paper presents a neural network-based maximum power point tracking (MPPT) controller for 1.26-kW proton exchange membrane fuel cell (PEMFC), supplying electric vehicle powertrain through a high voltage-gain dc–dc boost converter. The proposed neural network MPPT controller uses a radial basis function network (RBFN) algorithm for tracking the maximum power point of the PEMFC. High switching-frequency and high voltage-gain dc–dc converters are essential for the propulsion of FCEV. In order to attain high voltage-gain, a three-phase high voltage-gain interleaved boost converter is also designed for FCEV system. The interleaving technique reduces the input current ripple and voltage stress on the power semiconductor devices. The performance analysis of the FCEV system with RBFN-based MPPT controller is compared with the fuzzy logic controller in MATLAB/Simulink platform.
