Z parameters of the coupled inductors network

Circuit theory is very good tool to understand and calculate the WPT system. In order to understand what happens in the magnetic coupling in circuit theory, two port network theory provides us good knowledge. Let’s start discussion with the following figure. The figure shows the schematic of the 2-port network. the 2-port network will be anything such as band pass filter, transmission line or WPT system. We can describe this system with ABCD parameters. I recommend that you read the Pozar’s book to understand ABCD parameters first. One of the merits using ABCD parameters is that we can multiply each ABCD matrix when we deal with the cascade 2 port […]
