Hi there,
I am trying to design a power controlling circuit for a pump engine (consider as inductive load) as figure below
I use a pulse source to simulate output of the Arduino (5V - 100Hz). The problem is every time I run the simulation, the output of the MOC looks like wrong. The sine wave should be chopped at some points instead of a full wave.
The source is 325V Amplitude, 50Hz. U2 is 500 Vdm, 50mA Igt and 6A I max. R3 & C2, R4 & C1 are used for snubbing.
Can anyone tell me where I made mistakes?
Thanks,
