Abstract : This article investigates different currents, voltages and powers of four different step-down and four different step-up autotransformers fed sinusoidally for analytical and simulation conditions. In this paper, analytical modeling and equations for step-down and step-up autotransformer based on current point signal and voltage polarity are presented. A discussion based on their theoretical use is then presented in the simulation along with calculations regarding their power performances. These models are also validated by simulation results of current, voltage and power waveforms for each analytical case. PSpice program is used for this simulation.

Keywords : Autotransformer Modeling, Polarity. Autotransformer Simulation, Step-Down Autotransformer, Step-Up Autotransformer.
