The topological structure of a new type of static synchronous compensator, which consists of traditional 12-pulse converter and a cascaded H-bridge, is presented. The purpose of designing such a topological structure, which integrates the concepts of multi-level, soft-switching and re-injection, is to reduce the voltage harmonic content at AC side and to solve dynamic voltage balance among the switches connected in series.

Beginning with wave equation, the paper has deduced the propagation of gauss pulses in single mode fiber and fiber grating transmission compensation. The characteristics of cascaded phase-shift gratings are discussed by numerical simulations of coupled-mode theory and T-matrix method. The experimental works and measurement results are shown in this paper. On the other hand, we have introduced the basic theory of EDFA and figured out the characteristics for EDFA at different conditions by numerical simulation. Some experimental results for EDFA are also presented here. In this article, you can find the influence on Optical Fiber Amplifier by Gain Tilt, especially, the negative effect on CSO in CATV transmission system.

To eliminate common-mode voltage of cascaded multi-level inverter, three kinds of phase-difference SVM based on left and right bridge vectors are proposed firstly. From these three modulations, equivalent SPWM components are deduced, and the unipolarity and bipolarity of output waveforms are analyzed. 2π/3 PD-SVM (phase-difference space vector modulation) is testified be unipolar.
