Abstract :
A simulation based on system equations that demonstrates the advantages of nonlinear system partition, universal state-space equation solution, and modular system building is presented. The simulation package is built with a modular procedure in which each module is described using a state-space method and arranged in accordance with the physical power/signal process of the system. A detailed study of a single-phase AC/DC pulse converter (SPPC) feeding an inverter-induction motor drive system used in traction is carried out using the simulation. The necessity of the second-harmonic filter (SHF), which is commonly used in practical circuits, is investigated. A comprehensive and comparative analysis and a simulation study of the system, with and without the filter, are shown.<>
