Power converter controller with pulse pattern recognition

Abstract

A power converter controller with commands based on pulse pattern recognition is described. In one embodiment, a control system for a power converter includes a first switching circuit having a first controller, and a second switching circuit having a second controller. The second controller is configured to generate a pattern of pulses in a transmitted signal UTX. The pattern of pulses in the transmitted signal UTX corresponds to a predetermined command. The first controller is configured to receive a pattern of pulses in a received signal URX. The first controller includes a pattern filter configured for: comparing the pattern of pulses in the received signal URX with an expected pattern, and, when the pattern of pulses in the received signal URX corresponds to the expected pattern, asserting the predetermined command.

Dependencies are inferred from the claim text.
