Design of Real-time Embedded Control Signal Generator for Shunt Active Filter for Suppression of Harmonics

摘要

Recent advancement in new technologies have lead to the development of flexible, cost effective,' high performance electronic and electrical equipments. But they inject non-sinusoidal current, which distort the power supply voltage which may lead to malfunctioning, abnormal heating and vibrations in the equipment connected to network. Embedded system design involves choosing a right platform and the development support available from the vendor. The selection of the platform depends on processor, SOC, memory, Buses, software language, OS, code generating tools, simulators, emulators etc. Since, the decision on DSP processor is made, the chapter covers the hardware and software development support tools for the development of system hardware and software. The advantage of embedded control signal generator in real-time is to make nonlinear loads and active power filter in parallel to be an equivalent resistance. After compensation, source current is sinusoidal, and has the same shape of source voltage. Proposed controller is applied to a shunt active power filter experimental prototype based on DSP TMS320F6711.
