Characteristic analysis of contactless transformer
The mathematical model of reflected reactance supplied by voltage source is established to deeply analyze the coupling characteristic and power transfer characteristic of a contactless transformer used in angle sensor. Firstly, the molding method is studied based on the structure feature of contactless transformers with pot core. Then, the primary and secondary equivalent circuits of a transformer supplied by voltage source are obtained by using the mutual inductance model with contactless electromagnetic coupling structure. On the basis of which, the mathematical model of reflected reactance is derived, and the expressions of some characteristics parameters, such as voltage gain and output power, are obtained. Finally, the prototype of a contactless transformer is made according to the design parameters calculated by means of the finite element model. The experiment shows that the mathematical model can be used to accurately analyze the coupling characteristics and power transfer characteristics of contactless transformers.
