Parameter Estimate Modeling of Electronic Transformer

In the plane-topology description of multidimensional dynamic coupling relations between the distributed parameters of electronic transformer, the distributed inductance, capacitance and resistance are often lumped. An indirect method based on the step response of full-loaded electronic transformer, is developed for the lumped parameters estimate of leakage inductance, equivalent capacitance, iron loss equivalent resistance and coil resistance of the transformer. Results of experiments show that both the estimate accuracy and the simulation confidence are satisfactory
