Application of a high efficient voltage regulation system with MPPT algorithm

In this study, an integrated voltage regulation system including Maximum Power Point Tracking Algorithm (MPPT) is introduced to store and efficient use of the energy produced by renewable sources. A dsPIC is used as the main controller to obtain a rapid and stable decision-making system and to decrease the cycle time of the MPPT operation. In order to minimize the oscillations on the output voltage, a cuk converter is used that can be operated as both buck and boost modes. Thus, efficiency of the system has been increased considerably by storing the energy consistently. The experimental results validates that the system developed operates highly stable and is faster than the similar ones presented in recent literature.

► We designed a powerful voltage regulation system with MPPT application. ► We used dsPIC as the main controller and cuk converters to store the produced energy continuously. ► The system has very short response time against instant changes of input parameters. ► The system operates highly stable and faster.
