Platform Specific FPGA Based Hybrid Active Power Filter for Power Quality Enhancement

Abstract

Abstract Elimination of harmonics by the use of power filters is required for power quality improvement; provides a wide area for the researchers to develop efficient power filters with improved control platforms. This paper motivates the implementation of the embedded control platform for better control of the power filters for faster elimination of harmonics. Although many embedded processors fascinates the implementation of the control techniques but finding the feasible platform is a great task. Software implementations are feasible for most of the power electronics converters but the hardware design with required digital hardware is a challenging task. The present paper deals with the development of the control technique for the Hybrid Active Power Filter with Xilinx System Generator Platform. The virtual FPGA (Field Programmable Gate Array) platform provided by the Xilinx System Generator has the ability to generate better switching signals for the control of the power filter to generate compensating signal for elimination of harmonics to maintain the power quality in the distribution lines. Experimental results obtained by the setup developed in the Power System Laboratory presents the effectiveness of the Embedded Platform. Various source voltage conditions also simulated and performance is verified for the developed Hybrid Active Power Filter.
