Method and apparatus for controlling the output of an electrical consumer connected to an AC power voltage.

摘要

A device for controlling the output of an electrical consumer connected to an ac supply voltage whose output is changed by changing the phase control of the magnitude of the alternating current supplied to an electrical consumer such as an electric motor, and the ignition angle corresponding to the desired power consumption. The ignition angle range, which determines the phase control range toward a value greater or less than a given reference value, is changed, causing an asymmetry of the ignition angle with respect to the time between two continuous waves, causing the radix-harmonic to abruptly decrease when the superior harmonics slowly increase. do.
