| Abstract: | This paper analyses the relations between trigger circuit and load briefly on the basis of one-phase alternating adjustment circuit used by the temperature control part of Oxide Crystal Furnace which requests heating power is stable. It realizes the trigger function for the SCR reliable and the pulse width and interval unit in each cycle under the situation that the heater is not pure resistance. And it also ensures the oxide crystal growth successfully. |
