Study of a Synchronization System for Distributed Inverters Conceived for FPGA Devices

In a multiple parallel-connected inverters system, limiting the circulating current phenomenon is mandatory since it may influence efficiency and reliability. this paper, new control method aimed at purpose conceived to be implemented on Field Programmable Gate Array (FPGA) device presented. Each of inverters, connected in parallel, equipped with an FPGA that controls Pulse-Width Modulation (PWM) waveform without intercommunication others. The hardware same for every inverter; therefore, addition module does not require redesign, enhancing system modularity. has been simulated Simulink environment. To study its behavior improve method, simulations two have firstly conducted, then additional performed increasing complexity demonstrate quality algorithm. results prove ability proposed limit currents negligible values.
