Generalized system design and analysis of PWM based power electronic converters

In this paper a new way for designing and analyzing the PWM based converters is presented. Frequency domain analysis is used for performance evaluation and signals are reconstructed into the time domain wherever necessary. Frequency domain analysis does not need any initial conditions and directly determines the steady state solution. A specific case study of STATCOM is presented in this paper with step by step design and analysis for commercially available power devices. The analysis program is modular and can be easily adapted for various applications. MATLAB is used for the computation. Using the output of the program specifications for various components can be generated.
