Abstract:

Recent improvements in power electronics have made it possible to make high-gain, step-up, non-isolated converters with low output voltage ripple. These are very important for modern DC/DC converter applications. These converters are becoming more common in electric vehicle (EV) systems, where they are needed for efficient energy interfacing. In integrated power systems, high-gain step-up multiport converters are especially useful for connecting multiple sources like photovoltaic (PV) panels, batteries, and DC loads. Closed-loop non-isolated multiport buck-boost and boost converters are used to better control the load voltage and the speed of the DC motor. This paper talks about how to design and control a closed-loop controlled multiport converter. It compares the performance of Proportional-Integral-Derivative (PID) and Model Predictive Control (MPC) strategies. We look at the control schemes using important factors like settling time and steady-state error. A small-signal model is created to help with the design and study of the suggested converter. We use MATLAB simulations to check how well the system responds to changes and how reliable it is under different operating conditions. The results show that the suggested control strategies greatly improve the converter's performance, making them suitable for use in multi-source energy systems, such as electric vehicles (EVs) and renewable energy integration, that need precise voltage regulation and quick response to changes.
