Flame proving is called flame rectification. The board sends an AC signal to the flame sensor, the flame rectifies it, converting it to a DC signal. The board is looking for a DC signal to prove flame. Thermocouple works by 2 dissimilar metals creating a millivolt DC voltage (typically 15 to 32 MV DC) which holds a small magnet out of the path of the pilot gas supply. Thermocouple technology has been around over 100 years and doesn't require outside voltage to run. Flame rectification requires AC power of some kind to operate.
