Complementary architecture for verifying input data in redundant modules

Abstract

A system includes a first converter configured to receive a first signal and convert the first signal into a second signal. The system also includes a second converter configured to receive the first signal and convert the first signal into a third signal. The system also includes a control system configured to perform a verification operation on the second signal based on the third signal. The control system is also configured to perform a first diagnostic operation on the first converter during a first duration of time. The control system is also configured to perform a second diagnostic operation on the second converter during a second duration of time. The first duration of time and the second duration of time occur at different time periods. The control system is also configured to receive first complement data from the second converter during the first duration of time. The control system is also configured to receive second complement data from the first converter during the second duration of time. The control system is also configured to generate a fourth signal based on the second signal, the third signal, the first complement data, and the second complement data.
