Abstract :
This paper studies the FPGA-based control 4 H-bridge cascaded 9-level structure of voltage quality adjustment device, for the variety of voltage quality issues appears in electric power system, providing a comprehensive solution. With the voltage swell, voltage sag, voltage harmonics, voltage fluctuations which occurs in the power system, it can give out the complex compensation, so as to ensure the system voltage quality, 0.1MVA/400V Low-voltage prototype was designed and developed for validating the variety of experiments. Experimental results show that the design of this device is feasibility and effectiveness.
