Abstract :
An equivalent network of printed-circuit-board (PCB) based three-winding transformers is presented for simulating high frequency behavior (at some MHz). The PCB-based transformers do not require the manual winding procedure and thus simplify the manufacturing process of transformer-isolated gate drive circuits. The use of the multiple secondary outputs can simplify the complementary gate drive circuits that are often required in many power electronics applications. A systematic procedure is presented to deduce the inductive and the capacitive model that can be easily extended to multi-winding transformers. The numerical evaluation of the model parameters is carried on and the frequency response or the model is discussed.
