A Review and Design of Power Electronics Converters for Fuel Cell Hybrid System Applications

Electric vehicles (EV) are getting more commonplace in the transportation sector in recent times. As the present trend suggests, this mode of transport is likely to replace the internal combustion engine (ICE) vehicles in near future. Each of the main EV components has a number of technologies that are currently in use or can become prominent in the future. EVs can cause significant impacts on the environment, power system, and other related sectors. The present power system can face huge instabilities with enough EV penetration; but with proper management and coordination, EVs can be turned into a major contributor to the successful implementation of smart grid. There are possibilities of immense environmental benefits as well, as the EVs can extensively reduce the greenhouse gas emission from the transportation sector. However, there are some major obstacles for EVs to overcome before replacing the ICE vehicles totally. This paper is focused on reviewing all the useful data available on EV configurations, energy sources, motors, charging techniques, optimization techniques, impacts, trends, and possible directions of future developments. Its objective is to provide an overall picture of the current EV technology and ways of future development to assist in future researches in this sector.

“…Hence, hybrid fuel cell power conversion systems are well suited for the applications where the average power demand is low whilst load dynamics is relatively high [4]- [6]. For this reason, how to merge the different renewable energy source elements together as a hybrid power conversion system and control the power flows effectively has become a really interesting topic [3] during the last decade. Furthermore, in the grid-tie applications fuel cells are often faced with the need of boosting their low output voltage to the much higher DC-link voltage which is required for a single/three-phase utility grid [7].…”

“…Proton exchange membrane (PEM) fuel cells are considered as a good candidate for many applications, for example, automotive propulsion, due to their zero emission, low operating temperature and high power density [1]- [3]. Generally speaking, fuel cells can be implemented either as a standalone system or in combination with other power/energy sources such as a battery and/or a super-capacitor bank.…”

Abstract-This paper presents an isolated dual-input DC-DC converter with a PWM plus phase-shift control for fuel cell hybrid energy systems. The power switches are controlled by phase shifted PWM signals with a variable duty cycle, and thus the two input voltages as well as the output voltage can be regulated effectively. By using the second input capacitor and the high side switches as an inherent active clamping circuit, zerovoltage switching (ZVS) for the power MOSFETs on the primary side, and zero-current switching (ZCS) for the diodes on the secondary side are achieved respectively to improve the performance of the proposed PWM converter. The principle of operation is analyzed and some design considerations are discussed. Simulation results using PLECS are given to verify the proposed analysis and design. An experimental converter prototype has been designed, constructed and tested in the laboratory to verify the validity of the theoretical analysis and also demonstrate the converter's performance over wide variations in input voltage.

“…Hence, hybrid energy conversion systems are well suited for the applications in which the average power demand is low, whereas the load dynamics are relatively high [4]- [6]. For instance, [3] presented and compared different power electronic interfacing solutions for a reversible fuel cell with auxiliary power sources (APS) to overcome the drawbacks of fuel cell systems such as slow dynamics. Moreover, in order to efficiently regulate output voltage, which normally has large voltage difference from input ports, as well as to provide galvanic isolation, many fully or partially isolated three-port dcdc converters with high frequency transformers have been proposed and studied in recent years [7]- [14].…”

Abstract-This paper presents two configurations of dualinput (DI) or three-port (TPC) isolated dc-dc converters for hybrid renewable energy systems such as photovoltaics and batteries. These two converters are derived by integrating an interleaved boost converter and a single-active bridge converter with an ac inductor as a power interfacing element or phase-shift softswitching converter with an output dc inductor. Both converters are controlled by a pulse-width modulation and phase-shift hybrid modulation scheme. The two converter topologies are, even though quite similar from the topological and control perspective, distinct in operation principles, voltage/power transfer functions, loss distributions, soft-switching constraints, and power efficiency under the same operating conditions. Moreover, the inductor design differs greatly between these two cases. In this paper, a comprehensive comparison is given for the first time and thereby the corresponding design tradeoffs are discussed. Finally, a laboratory 1 kW prototype is constructed and tested to verify the theoretical analysis.
