A Non-isolated PV Quadratic Bi-directional Converter with Closed-Loop Operation of a Drive Using Fuzzy Controller

摘要

In this lavishing and developing technology era, the conventional methods are updated and made them more effective for the usage. Here, the boost converter is the device which increases the voltage from one end to another end. It is the conventional method for everyone to increase the DC-DC voltage. The level of increment will be obtained by varying duty ratio. To make a boost converter more efficient, we can apply cascading property. The application of the cascading property is known to be quadratic boost converter. The quadratic property increases the input voltage to the output voltage ratio by 1/(1-D)~2. In the same way, the bi-directional converter is more effective than the boost converter because of its charging and discharging properties according to their applications. The components used for the proposed quadratic boost converter [ 1 ] are more in number than the bi-directional converter in the quadratic property. So, the proposed quadratic bi-directional converter has both quadratic boost and quadratic buck methodology. The renewable energy is mainly used as a source, showing the closed-loop control using motor drive for bi-directional converter in the form of discharging mode and charging mode with the fuzzy as a switching technique.
