faskontroll
Faskontroll is a method for regulating alternating current power by controlling the phase angle at which power is delivered to the load during each half-cycle of the AC waveform. By delaying the triggering of a switching device, typically a thyristor or triac, the conductor conducts only part of each half-cycle, reducing the effective voltage and the average power delivered to the load.
In a typical faskontroll circuit, a control circuit advances the firing angle of the device from near
Applications of faskontroll include light dimming, radiant heating elements, and small universal motor speed controls, where
Historically, faskontroll became widespread in consumer electronics during the mid-20th century with the advent of SCR-based
