Design of Master-Slave Active Power Filter Control System Based on Concerto+FPGA

According to how to seek a balance between powerful loop control and communication functions in the master-slave active power filter, this article constitute a control and communication system with It's latest Concerto F28M35x and FPGA. Concerto F28M35x series processor combine C2000 C28x core with Cortex-M3 core in a device, which have both real-time control and advanced connectivity, By researching the current-voltage control strategy of each module, it realizes the output of harmonic current and reactive current with a master-slave active power filter which consists of a main cabinet and a sub-cabinet that in parallel operation. Experimental results prove that master-slave structure which Based on Concerto + FPGA is feasible. After being compensated, output current of each module is the same, the harmonic distortion rate is low, and the response speed is fast.
