Modelling of Constant Voltage Transformer for Transient and Parametric Analysis

This paper present a model of a Constant Voltage Transformer (CVT), with consideration for transient and parametric simulation. The interaction of the ferroresonant circuit and the geometric parameters such as windings, capacitor, and shunt reluctance on the CVT performance is studied, and the determination of the parameters for a better operation is achieved. This model is implimented with Matlab/Simulink where the behaviour of the nonlinear reluctances is modelled by a simple hysteresis model with considering of the core loss. The experimental results are compared with the simulation results under different conditions to validate the implemented model.
