Electrical filters--Computer simulation


This thesis gives a detailed description of a rea -time simulation of a highfrequency, high -order, low-pass power filter on the analog and digital computer. The single element flow graph (SEFG) procedure was developed whereby there is control on each and every element of the system. Several examples are introduced to the effectiveness of this method. The SEFG procedure is applied to the analog and digital simulation of a single-phase, high-order filter. The frequency and time domain responses are acquired from these simulations and several examples are presented to demonstrate the SEFG equation sequence to avoid divergent solutions. Several types of digital simulation are introduced using the SEFG procedure. The effectiveness of each type are compared. The concept of modular simulation is applied to a tenth-order low -pass filter. The time domain analysis is derived using a digital simulation with the SEFG procedure. The results also include a fault analysis in the frequency domain whereby the filter performance is determined for variation in the filter elements.
