“…This makes it possible to write a program which can be used to automate the derivation for the general case. The analysis procedure has been automated in a power electronic circuit simulator, named PECS [3]. Now instead of facing a tedious job of deriving the transfer functions for a specific converter, one can easily use the available CAD application to perform the dynamic analysis.…”

“…In contrast, most of the other specialized switched-circuit simulators are based on state-space equations [1]- [4], which may result in somewhat smaller system matrices and more efficient time iteration based on the state transition matrix expansion. The potential benefits of the state-space approach diminish when the considered network includes arbitrary independent sources, large number of states, or smooth nonlinear elements.…”

This paper describes PETS (Power Electronics Transient Simulator), a program for timedomain analysis of power electronic circuits. Methods implemented in PETS include standard techniques such as the modified nodal approach to forming system equations, and numerical integration with automatic time-step control, together with new techniques including a state determination algorithm, and representation of elements to maintain a constant system matrix. The simulator supports arbitrarily complex piecewise-linear models and smooth nonlinear models using a delay approximation. The methods implemented in PETS are illustrated using two examples: a quadratic buck converter, and a closed-loop powerfactor corrector.

Current development trends in the area of switching power converters such as rising integration, increasing power density, and the growing complexity of power converter systems have indicated a strong need for a new class of simulation tools which would allow for a complex approach to solve the problems of converter analysis and design.Such an approach, besides being a fast and accurate simulation of the switching waveforms of the converter, should also include an overall analysis of converter behavior in response to changes in operating conditions, a search for extreme values of internal variables of the converter circuit, computation of power dissipated by particular devices, calculation of efficiency, ac analysis, sensitivity analysis, and design optimization. The role of determining the steady-state with the resulting algorithms is crucial.Research in the area of numerical analysis of switching power converter circuits has been traditionally focused on the operation of a single power converter. However, growing demand for integrated high-power-density solutions requires this analysis to expand beyond the domain of one converter and capture the interaction of all power converters in the network.In order to better address the needs of development and practical design, this thesis presents alternative simulation techniques which can be used for the analysis of networks consisting of multiple switching converters. The focus of this work is the area of steadystate analysis. Two new methods for the efficient determination of switching power converter steady-state are presented. These new methods simplify the algorithm structure by reducing the number of iteration loops and effectively address the convergence issues iii seen with published methods. Furthermore, the proposed algorithms are extended to cover the area of networks with multiple switching converters. Particular focus is on the development of general methods for the modeling and simulation of networks with multiple switching power converters in both the time-domain and frequency-domain. iv
