Method for operating a universal motor and household device for caring for pieces of laundry

摘要

The method involves switching an alternating voltage network and controlling an inductive load. Variable firing angle of a semiconductor plate is determined according to an instantaneous load behavior of the inductive load. A maximum instantaneous firing angle is determined according to the instantaneous load behavior of the inductive load. An independent claim is also included for an ignition switch for a switchable semiconductor plate.
