Abstract
A controller for a semiconductor switch is described that includes a transmitter and a receiver that communicate across galvanic isolation using an inductive coupling. An example controller includes first circuitry referenced to a first reference potential, second circuitry referenced to a second reference potential and galvanically isolated from the first circuitry, and an inductive coupling galvanically isolating the first circuitry and the second circuitry. The inductive coupling includes a first winding referenced to the first reference potential and a second winding referenced to the second reference potential, wherein the first circuitry includes signal reception circuitry coupled to the inductive coupling, wherein the signal reception circuitry includes one or more signal receivers coupled to the first winding to receive signals transmitted over the inductive coupling.
