PV inverter control using a TMS320F2812 DSP
نویسندگان
چکیده
This paper presents the implementation of a control system of an inverter for grid connected photovoltaic (PV) applications, using a low cost TMS320F2812 eZdsp board. The implemented control system contains a P+Resonant current controller, a Maximum Power Point Tracker (MPPT) to optimize the power extraction from the PV panel, and a Phase Lock Loop (PLL) for grid synchronization. The whole control was implemented in fixed point using Simulink. Code Composer Studio is successfully used as a flexible user interface for controlling and monitoring the process. The experimental results show that this low cost DSP is capable of running a complex control structure in real time at a high sampling rate. In this case a current THD close to 1% and a high efficiency MPP tracking has been achieved.
