Recent trends in control and converterSummary: new single switch solar powered high gain step-up DC-DC converter is proposed for plug-in hybrid battery charger in Electric vehicle (EV). The proposed topology utilizes a L2C3D2network to obtain high voltage gain and reduce the voltage stress on the power switch. Also, the proposed converter has a universal input voltage to suit the soft output attributes of the fuel cell. The fuel cell has a relatively low output voltage and high current, and it has soft output characteristics as its output voltage drops as the output current increases. Accordingly, the fuel cell can't be straightforwardly interfaced to the dc- link bus (400V) of the inverter inside the EV. This dc-dc converter has a universal input voltage feature with wide voltage gain range to suit the soft output characteristics of the fuel cell. Also, this dc-dc converter must have low input current ripple to delay the existence time of the fuel/solar cell, and a shared ground between its input and output ports to keep away from extra EMI and support security issue. This control strategy is modelled and simulated using MATLAB -Simulink. A proto type experimental has been fabricated and tested. The experimental analysis was done and the results are in line with the simulation results.
