A transformer is a two part system of two inductive coils. If you open the circuit on one end, the closed end won’t be able to induce a current into the second coil. It’s as simple as a single MOSFET controlled by some power management IC that measures current to prevent this from happening. It’s easier to prevent damage from wireless charging than it is from a physical connection. |
