A smart FPGA based design and implementation of grid connected direct matrix converter with IoT communication

Recent innovation in Internet of Things (IoT) is viewed as a fundamental base for power electronics converters. IoT gadgets have characteristically restricted responsiveness that may not be sufficient period for basic signal generators with stringent requests on correspondence delay. Practically denoted, it remains a remarkable issue to consolidate IoT innovation with existing grids. This paper demonstrates a smart IoT system is used for a Matrix Converter and it is based on the Neutral Point Clamped converter is introduce to minimize the currents harmonics in input and output side. The three stage output voltage is taken to the matrix converter and this power utilized in the medium voltage high power applications. The converter operation and control strategy are prepared using Robust Grid Unbalanced Control Technique. In inverter is based on Neutral Point Clamped structure and the main part of the system and its give the zero current with neutral point in this circuit. The Direct Current (DC) link is not controlled in the existing topology, but this operation is possible to the proposed bi-directional capacitor system to control the DC link. By using Robust Grid Unbalanced Control (RGUC) Technique, the Matrix Converter parameters are continuously loaded to IoT server. The effectiveness of the proposed structure of Robust Grid Unbalanced Control is validated by using simulation and hardware results and achieved overall 98.53% efficiency in this proposed control technique. This implementation of RGUC based matrix converter is also carried out using low cost but powerful FPGA and the experimental results obtained are compared with those obtained through simulation.
