This paper investigates the operation of a sinusoidal supplied autotransformer on the different states of magnetic
polarity of primary and secondary terminals for four different step-up and step-down analytical conditions. In this paper, a new
analytical modeling and equations for dot-marked and polarity-based step-up and step-down autotransformer are presented.
These models are validated by the simulation of current and voltage waveforms for each state. PSpice environment was used
for simulation
