A Very Fast Method for Solving Electrical Circuits with Nonlinear Resistive Elements
Abstract
We present an improved version of the Hănțilă Method (HM) for circuits with multiple nonlinear resistive elements (NRCEs). The method replaces NRCEs with generators consisting of linear resistors and nonlinear controlled sources, whose values are updated iteratively. At each iteration, the resulting linear circuit is solved in the frequency domain for each harmonic. We evaluate the computational effort and compare computation times and results with those obtained using conventional methods applied to a circuit comprising parallel-connected single-phase half-wave rectifiers.
