Phase Fired Controllers

Phase Fired Controllers

Phase control (PFC), also called phase cutting, is a method of pulse width modulation (PWM) for power limiting, applied to AC voltages. It works by modulating a thyristor, SCR, triac, thyratron, or other such gated diode-like devices into and out of conduction at a predetermined phase of the applied waveform.

Famous quotes containing the words phase and/or fired:

    It no longer makes sense to speak of “feeding problems” or “sleep problems” or “negative behavior” is if they were distinct categories, but to speak of “problems of development” and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.
    Selma H. Fraiberg (20th century)

    I worked as a waitress till I was fired because I dumped a cup of hot coffee in the lap of a half-drunk guy who was pinching my butt.
    Juli Loesch (b. c. 1953)
