This paper suggests a new high-gain three-port converter using fuel cell, battery plus stacked output designed for HEV coupled todc-micro grid. In the anticipated converter, load power can distribute flexibly among input sources. The battery charging, discharging be controlled using FC. The anticipated converter output sare in series to attain a high output voltage, makes it suitable to interface with HEV and dc-micro grid. Going on with charging, discharging conditions of battery, two modes are well defined. The anticipated power converter contains one boost inductor combined using fly back transformer; the boost and fly back circuit output terminals are stacked to rise output voltage gain and decrease voltage stress on the power devices. PV is combined to DC-DC converter to get high performance can be analyzed by using MATLAB/SIMULINK model.
Nowadays renewable generation methods attain more attention owing to exhaustive nature of fuels and its bigger prices. Also the necessity for pollution free green energy has made a strong attention towards alternate energy sources. Solar energy stands the most available renewable source to encounter our fast growing energy desires .Peak power from PV unit is to be traced for its effective application. Several processes are obtainable in literature for tracing maximum power from solar panels. Modern improvements in renewable energy built power systems, HV’s, aerospace systems, RES built smart grids and portable devices have brought challenges to design new DC–DC conversion systems. This method composed of numerous input sources, combined through a multi-input power converter that can put up variety of input sources besides combine their benefits to provide measured output for varied applications . EV’s are the agents in charged transport, and this invention is currently evolving rapidly . EVs have an excellent power profile that has both force usage and recovery at several moments of its process . DC-DC converters are interfaced with power supply to load. On the basis of load desires, the parameters of source are adjusted. In conventional technique, each source of energy is coupled by its individual DC-DC converter whereas in multi-port DC-DC bustechnique, a single control for the multiple inputs, output ports .
This paper anticipated a three-port converter with high gain, stacked output is simple in structure. The anticipated converter obtains the HEV electrical power from FC, battery sources then changes it to a suitable high voltage, which is applied to dc-micro grid so that dc home usages canusetheelectricitydirectly.Thecircuitoperativeprinciplesanticipated converter in battery discharging, charging modes were presented. The strength of anticipated power converter its performance was verified through simulation results. The charging, discharging battery storage device be controlled efficiently by means of FC source.
