Design of Capacitive Coupled Transformer for Power Converter Applications

In this paper, power transfer will be made with a capacitive coupled transformer structure. Inductive transformers are difficult to produce and take time because a certain number of turns are required. Instead of an inductive transformer model, a capacitive transformer model will design and test. This device will transfer power with an electric field. Four conductive layers are being in the same dielectric material in a nested structure, the power transfer will be transferred from the primary to the secondary. It is expected that the capacitive transformer model here will be better than the inductive transformer in terms of manufacturing convenience. This design will provide a function of a step-down transformer and also provide isolation between primary and secondary sides. The simulation study was performed with MATLAB Simulink, and power transfer was performed as desired. Similarly, the experimental circuits were set up and the results were taken from the oscilloscope.
