A fuel cell-based hybrid power supply for portable electronics devices
2008
A fuel cell - supercapacitor hybrid power supply for portable applications is designed. To ensure system level simulation, each component is accurately modeled and simulation results are reported. A Digital Still Camera is selected as specific load device, although the choice of a specific application does not influence the proposed control technique performances but only dictates the power supply specifications. The fuel cell and the power management system are modeled in PSIM. © 2008 IEEE.
A fuel cell-battery hybrid power supply for portable applications
2010
Today, academic and industrial research is addressed to fuel cell based hybrid power supply in many fields of applications including stationary, automotive and portable electronics. Increasing source runtime, speeding up the transient response while minimizing weight, volume and cost of the power supply system are key requirements of all applications. According to the particular application, the power management system is optimized for a specific feature. In this paper, a fuel cell–battery hybrid power supply for a Digital Camera is proposed, although the control algorithm can be efficiently applied to any portable device. Thanks to an innovative control on the input power, any fuel cell pr…
High Accuracy Modelling of Hybrid Power Supplies
2011
This chapter proposes a modelling approach based on the PSIM/Simulink co-simulation toolbox for hybrid power supplies, featuring high accuracy. Hybrid source performances are fully tested during behavioural simulations. The importance of high-accuracy modelling is investigated and modelling guidelines for both power sources and load are given for further applications. The Simulink model is analyzed and the efficiency of the proposed approach is verified by the comparison between simulation and experimental results. In the last few years, hybrid power supplies are investigated for a wide variety of application areas: two primary sources are coupled to take advantages of both, overcoming thei…
