Respecter sir/madam,

As I am doing my project in soft switching bidirectional dc to dc converter and I am in very much of confusion to write matlab simulation. Please kindly do me a favor of this and send me the simulink result and matlab code together and do needful.

Thanks and regards,

Since the fuel cell system has slow dynamics of nature, it is recommended that you have an additional auxiliary power, for example, ultra-capacitors or batteries during the transition to improved performance in energy and transport applications. The use of ultracapacitors and bi-directional converter with a fuel cell system may be one of the possible solutions to the problem of slow dynamics of fuel cell systems. In this article we present a combined small AC signal equivalent circuit model of bidirectional converter in PEM fuel cell, and the cell with the aim to develop a corresponding controller for bi-directional converter. Transient performance of the entire system, including the fuel cell model, the ultra capacitor and bi-directional converter modeled in Matlab Simulink environment.
