Dynamic Modeling of Six Pulse Rectifier Using MATLAB
Journal Title: International Journal of Science and Research (IJSR) - Year 2013, Vol 2, Issue 7
Abstract
"A dynamic modeling of thyristor rectifier which is useful for the study of power electronics controlled rectifiers with the help of using MATLAB and SIMULINK is presented in this paper. This dynamic model is very simple, fast and effective simulation method for the output variables of thyristor rectifiers. The rectifier output voltage static and dynamic variables behavior are represented by an accurate non linear function of the pulse number (p), trigger angle control voltage (?) and displacement angle (?). And also it allows the study in open and closed loop thyristor rectifier simulation of loads which are fed by high power thyristor rectifiers with any pulse number greater than one (p>1) or their association by solving only the differential equation(s) of the load(s). The simulation time is always small and independent of the pulse number. This paper gives an approach to establish a general pulse(p>1) thyristor rectifier dynamic model which is based on the steady state rectifier behavior and corrected to accurately represent its dynamic transients. In this paper we considered only null commutating reactances having instantaneous switching, no conduction loss and zero overlap angle. "

Performance Analysis of Shunt Active Power Filter with Different Switching Signal Generation Techniques
The performance of shunt active power filter (SAPF) is compared for steady state load condition. The SAPF is used for harmonic compensation of single phase ac/dc converter feeding a nonlinear load. The process involves a...
A Tool to Measure the Behavioural Competency of Under Graduate Students
Behavioural competency refers to personal attributes or characteristics (i.e. motives, attitudes, values) that describe how a job or task is performed as opposed to the particulars of the job or task. For instance, compe...
Space Debris Low Earth Orbit (LEO)
Humans have created a lot of garbage on earth surface to which we can see, but up in the atmosphere, unbelievably the amount of junk human have created in space is equally colossal. The main topic of this paper is to dis...
