Flyback converter with reliable pulse-based isolated communication
An isolated switching power converter communication channel is provided that comprises a pair of capacitors. A transmitter on a first side of a transformer for the converter transmits a transmitter signal over a first one of the capacitors. The transmitter also transmits a complement of the transmitter signal over a second one of the capacitors. A receiver on a second side of the transformer recovers a signal responsive to a high-pass-filtered difference of the received signals from the pair of capacitors.
