Hardware In The Loop (HIL) MATLAB/Simulink Co-Simulation Of Shunt Active Power Filter

Abstract

Semiconductor circuit elements constitute the cornerstones of software power electronics applications, including the central control unit (MKB) and the algorithm. Faults that may occur in the central processing unit can damage the semiconductor elements on the plant. Therefore, the hardware-assisted simulation of the software prepared for a power electronics application before the experimental study by using the processor hardware itself will be useful. In this study, the common simulation model of the Shunt Active Power Filter (SAPF) system is prepared in Simulink, tested by using digital signal processor (DSP) software and hardware, and compared with the simulation results without hardware. The voltage and current data coming from the power stage in Simulink simulation to the DSP are processed here and the control signals are created in the hardware, these signals created in the DSP are taken into the Simulink environment and applied to the inverter part of the prepared model. This hardware supported common simulation model, in which software testing of the DSP is performed before the experimental study, prepares a common simulation environment for other power electronics applications. Hardware supported 3-phase SAPF co-simulation model in the loop was prepared, tested in Matlab / Simulink environment and simulation results were presented.
