Abstract:
This paper evaluates four different variable transformer configurations considering their leakage inductance, magnetizing inductance, and achievable input-output voltage ratio. Simplified electric models are obtained by analyzing the magnetic circuits and their correspondent dual electric representation. These models are verified and validated with simulations and experimental tests obtained by lab measurements. The methodology adopted in this work allows getting simplified electric equivalent for variable transformers having one primary and multiple windings connected in series in the secondary, easing comparison procedures among different topologies.
