The present paper is dedicated to a new type of analysis of an autotransformer discrete alternating voltage regulator presented as a two-port with a load. The ABCD parameters of the transmission matrices were determined by using a simulation model of the regulator in the environment of MATLAB, which includes four semiconductor commutation elements (thyristor switches), corresponding to different supply voltages and considers the nonlinearities of the regulator's circuit. These ABCD parameters can be used for quick and accurate analysis of such a device in case of arbitrary type of the load - active, inductive or capacitive. The received results were experimentally verified in the case of an active load and a good coincidence less than 1% was achieved.
