Abstract

A signal transmission system for communicating across galvanic isolation. The signal transmission system includes first circuitry referenced 108 to a first potential, the first circuitry comprising signal transmission circuitry, second circuitry 110 referenced to a second potential and galvanically isolated from the first circuitry, the second circuitry comprising signal reception circuitry, and a magnetic coupling 112 between the first circuitry to the second circuitry across the galvanic isolation, the magnetic coupling comprising a transmitter-side inductor and a receiver-side inductor. The signal transmission circuitry can include a source coupled to output, to the transmitter-side inductor of the magnetic coupling, a first state representation that represents a first logic state with multiple transitions, the first state representation including at least a first upward transition, a first downward transition, a second upward transition, and a second downward transition.

Description

technical field [0001] The present disclosure generally relates to communication between a receiver and a transmitter across galvanic isolation using an inductive coupling, such as in the case of a power converter in which the primary side is galvanically isolated from the secondary side. Background technique [0002] Electronic equipment in many cases includes a communication system that sends information between a transmitter and receiver that are galvanically isolated and thus referenced to different ground potentials. Examples include power converters, medical equipment, marine equipment, and similar equipment. [0003] One such communication system utilizes magnetically coupled wires to send information between a transmitter and receiver. Inductive couplings are also known, in which a varying current flowing through a transmitting conductor induces a varying voltage across a receiving conductor. Coupling between conductors can be enhanced in a number of ways. For exa...
