Heating control system which minimizes AC power line voltage fluctuations

摘要

An electrical heater control system with reduced flicker comprising: an electrical heating system; an AC (alternating current) power source for supplying AC current to said electrical heating system; an AC power control device connected between said electrical heating system and said AC power source for controlling the supply of AC current to said electrical heating system; and a controller unit coupled to said AC power control device for activating said device at zero crossings of said AC power to minimize flicker in AC current supplied to said electrical heating system from said AC power source.
