Design and implementation of power convertor circuit toward electric vehicle charging applications

To protect conventional energy supplies and maintain the sustainable growth of society, electric vehicle charging stations connected to the network are combined with renewable energies. The green (renewable) energy storage system in the charging stations not only allows for uncomplicated charging but also allows for quick grid demand variations. The instability of renewable energy is the key obstacle in this notion. As the charging station's energy storage system is directly connected to a solar panel or other renewable energy source, the converter should be able to produce a regulated output of the necessary magnitude in response to fluctuating and insufficient input power. Under circumstances of high gain, using a traditional converter for this purpose will lead to low charging efficiency. This work submits a hybrid synchronous back (HSB) converter to compensate the mentioned issue. The maximum efficiency is handled for a variable input range of 15–45 V to offer 14 V in term of output voltage. The work is validated by design a 200W HSB converter prototype.
