In this paper the Synchronous Reference frame PI-based control method for generating the reference signals for the Voltage Source Converter of Shunt Active Power Filter (SAPF) is presented. The method relies on the performance of the Proportional-Integral (PI) controller for achieving the best control performance of the SAPF. To improve the performance of the PI controller, the feedback path to the integral term is introduced to compensate the winding up phenomenon due to the integrator. Using Reference Frame Transformation, reference signals were transformed from c b a stationery frame to q d 0 rotating frame. Using the PI controller, reference signals in q d 0 rotating frame were controlled to get the desired reference signals for the Pulse Width Modulation. Using MATLAB/SIMULINK, the 5 th , 7 th , and 11 th harmonics were used to test the proposed Active Power Filter with improved PI controller resulting in harmonic content down to 3.87%.

Passive Optical Network (PON) and Mobile Worldwide Interoperability for Microwave Access (WiMAX) are two emerging broadband technologies for the next-generation (NG) access networks. Integration of PON and Mobile WiMAX might be an efficient solution to broadband network access that can take advantage of the bandwidth benefit of fiber communications, and the mobile and non-line-of-sight features of wireless communications. By leveraging the advantages of both of these access technologies combined on an integrated architecture platform, NG converged-access solutions can meet the demand for mobility, bandwidth, reliability, security, and flexibility. By combining the practically unlimited capacity of optical fiber networks with the ubiquity and mobility of wireless networks, NG Fiber-Wireless (FiWi) networks will enable the support of a wide range of emerging and unforeseen fixed-mobile applications and services independent of the access infrastructure. PON and 4G Mobile WiMAX integrated architecture enables differentiated bandwidth allocation to end users that can provide more network capacity at reduced operational cost as compared to other existing technologies.
