The AC control circuit consisting of photocouplers

This is a AC control circuit consisting of photocouplers. The circuit is fixed with photocouplers, making the control circuit and the high voltage circuit separate the electric. The DC power supply of 5-24v/10mA controls the power of AC. When the AD voltage is over 0, VS2 gets through/cuts the line, therefore, when it is through, the current raising ratio of VS2 is low, so the high-frequency noise can be impeded. As the characters of load control are different, so the applied voltage source is not like the phase of VS2 current.
