Digital simulation of parallel inverters

Previously, a model of a nonlinear inductor exhibiting hysteresis loops was proposed, and successfully applied to typical nonlinear electric circuits [1]. This model is now generalized to include the nonlinear transformer, and applied to the digital simulation of parallel inverters. Comparison of experimental results with simulated results shows that the model taking into account the hysteresis loops behaves just like a physical inverter including the unstable operations.
