In any case of rectification—single-phase or polyphase—the amount of AC voltage mixed with the rectifier’s DC output is called ripple voltage. In most cases, since “pure” DC is the ...

Flame rectification is a phenomenon in which a flame can act as an electrical rectifier. The effect is commonly described as being caused by the greater mobility of electrons relative to that of positive ions within the flame, and the asymmetric nature of the electrodes used to detect the phenomenon. This effect is used by rectification flame sensors to detect the presence of flame.
