Haar state equations for power electronics system modeling

The authors extend to this work some considerations on the Haar analysis of switching circuits introduced in previous papers. Specific properties related to matrices associated with the analysis and the resolution of linear time-variant circuits, have been used to perform such study and define transient behavior for the line current of a power electronic device. The simple recursive algorithm for the construction of the integral and convolution matrices and the topological matrix has been applied to evaluated more in depth the most interesting features of the system. The example describing the application of such technique to a three-phase inverter provides also significant starting points for future research
