Dispersion Compensation Filter Design Optimized for Robustness and Power Efficiency

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Power-Efficient Time-Domain Dispersion Compensation Using Optimized FIR Filter Implementation

We investigate fixed-point aspects and time-domain ASIC implementations of CD compensation. An optimized implementation gives significant power dissipation reduction for short links, with further reduction if pulse shaping is considered.

Active Power Filter Design by a Novel Approach of Multi-Objective Optimization

This paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. The power filter integrates a passive power filter which is a RL low-pass filter placed in series with the load, and an active power filter which comprises an RL in series with an IGBT based voltage source converter. The filter is assumed...

Control of DVR by Fuzzy Controller to Improve Voltage in Distribution System

With the development of critical loads, power quality problem has become particularly important and poor power quality will be cause many adverse effects and the cost of many deaths will follow. To improve power quality and protection of sensitive loads against grid disturbances have been used new equipment based on power electronics similar FACTs devices, they are Custom Power. One of the most...

Energy-Efficient Chromatic Dispersion Compensation for Coherent Fiber-Optic Receivers

DSP-based chromatic dispersion compensation accounts for a large part of the overall power dissipation in fiber-optic receiver ASICs. We have implemented and evaluated compensation filters based different design methods using a MATLAB-based coherent fiber-optic system model in respect to compensation performance, filter length, and fixed-point aspects. Possible power savings when taking into ac...
