Abstract
The main objective of this work is to describe a unique modeling approach to the analysis of nonlinear magnetic devices coupled to electronic switching circuits. The modeling approach presented here is unique compared to the work of others since this is the first time the coupled problem is addressed using three-dimensional nonlinear transient finite element analysis. The modeling approach makes use of zero-dimensional finite elements and a transfer function to model the external circuit components. Three circuits are examined in the thesis. The three circuits are: (1) a half-wave bridge rectifier, (2) a buck regulator ( dc to dc converter), and (3) a transformer system. The first two circuits consider only circuit elements. However, in the third system a voltage excited transformer is examined which has a 1 to 1 turns ratio. Three load cases are considered for the transformer system; (a) no-load, (b) linear load, and (c) single phase half-wave rectifier. Both linear and nonlinear magnetic analyses are performed for the three transformer load cases. The transformer system for the linear no-load case is validated by comparison to a closed form solution. The two circuit models are validated using the well known circuit analysis software package PSPICE.
