If exchange is not possible customers will receive their money back. In comparison to a control by wave trains which would provide for, in the same case, a conduction of the thyristors of 3 successive alternations followed by gradsteur periods of non-conduction, it is understood that the ripple of the average voltage or average current, is less.

Regulating the power delivered into resistive loads powered with alternating current is conventionally effected by means of dimmers single or three gradateir, generally constituted according to the distribution of the phases, by a parallel thyristors mounted head to tail or a combination thyristors and diodes.
