This paper presents two variable time-step algorithms for time-domain simulation of electromagnetic transients. The first one has been created to simulate basic switching transients and the second one is intended to simulate power-electronic systems. Each algorithm is tested in a dedicated circuit. Simulation results yield excellent accuracy and significant improvements in computation time when compared to fixed time-step algorithm.
