A Comparison Study of Solid State Transformers Using Different Switching Techniques
Journal Title: UNKNOWN - Year 2013, Vol 2, Issue 7
Abstract
This paper investigates different switching frequency based pulse width modulation techniques which can minimize the total harmonic distortion and enhance the power quality from solid state transformer. Solid state transformers are important for various power electronics applications such as flexible AC transmission systems, next generation carriers and power system applications. Four methodologies adopting the constant switching frequency, variable switching frequency, constant pulse width modulation and variable pulse width modulation concepts are proposed in this paper. MATLAB/Simulink has been chosen to implement these techniques due its fast proto typing, simple hardware and software design. The simulation and experimental results are presented.
