“…Another disadvantage is the need for special consideration of power converters, because the output voltage of a fuel cell presents important variations under normal operational conditions. However, this issue has been addressed by experts in the last decade [15][16][17][18][19][20][21][22][23].…”

The aim of this chapter is to present an outlook about implementation of a range extender system based on fuel cells for battery electric vehicles. Such a system is highly feasible to be implemented in electric vehicles, in particular those used by beverage industry in city centres. The tourism is another industry that uses electric vehicles, for instance in resorts, hotels, airports, zoos, etc. As well, public transportation is another sector involved with this vehicular technology. These sectors are all the time looking for high efficiency and low costs; however, they also need to extend the range of the vehicles to fulfill some logistics requirements in a route. This chapter presents a numerical example for illustrating an implementation of fuel cell range extender system. Advantages, disadvantages, and business opportunities in fuel cell technology are presented.

“…Those converters have the features of simple structure, high voltage gain, and low cost, nevertheless, the problem of voltage gain inflexibility still exists. In the most current trend, switched capacitor and coupled inductor techniques are adopted to design high step-up converters [15][16][17][18][19]. Those high step-up converters have their own advantages and disadvantages, and result in a compromise between power component count, voltage gain, current stress, voltage stress, and power rating.…”

Integrated Three-Voltage-Booster DC-DC Converter to Achieve High Voltage Gain with Leakage-Energy Recycling for PV or Fuel-Cell Power Systems

Abstract:In this paper, an integrated three-voltage-booster DC-DC (direct current to direct current) converter is proposed to achieve high voltage gain for renewable-energy generation systems. The proposed converter integrates three voltage-boosters into one power stage, which is composed of an active switch, a coupled-inductor, five diodes, and five capacitors. As compared with conventional high step-up converters, it has a lower component count. In addition, the features of leakage-energy recycling and switching loss reduction can be accomplished for conversion efficiency improvement. While the active switch is turned off, the converter can inherently clamp the voltage across power switch and suppress voltage spikes. Moreover, the reverse-recovery currents of all diodes can be alleviated by leakage inductance. A 200 W prototype operating at 100 kHz switching frequency with 36 V input and 400 V output is implemented to verify the theoretical analysis and to demonstrate the feasibility of the proposed high step-up DC-DC converter.

Adaptive and Nonlinear Control Techniques Applied to SEPIC Converter in DC-DC, PFC, CCM and DCM Modes Using HIL Simulation

Abstract:In this paper, we propose adaptive nonlinear controllers for the Single-Ended Primary Inductance Converter (SEPIC). We also consider four distinct situations: AC-DC, DC-DC, Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). A comparative analysis between classic linear and nonlinear approaches to regulate the control loop is made. Three adaptive nonlinear control laws are designed: Feedback Linearization Control (FLC), Passivity-Based Control (PBC) and Interconnection and Damping Assignment Passivity-Based Control (IDAPBC). In order to compare the performance of these control techniques, numerical simulations were made in Software and Hardware in the Loop (HIL) for nominal conditions and operation disturbances. We recommend adaptive controllers for the two different situations: Adaptive Passivity-Based Feedback Linearization Control (APBFLC) for the PFC (Power Factor Correction) AC-DC system and IDAPBC-BB (IDAPBC Based on Boost converter) for the regulator DC-DC system.
