This contribution provides comprehensive development procedures and mathematical models of an adjustable speed drive (ASD) for steady-state solutions. A complete representation of the ASD is employed, which includes the detailed models of the diode rectifier and of the inverter. The power electronic switches are efficiently represented through a smooth function that allows a larger integration step to be used without loss of precision in the solution. An efficient technique in the time domain for the computation of the periodic steadystate solution of electric systems including ASDs based on a discrete exponential matrix (DEE) and the Poincaré map is used. Simulation results are compared with the data obtained in an experimental prototype. © 2010 IEEE.
