Now I got the parts and it's working!! well partially, I just did the first set of scr, Also I added a diode(thanks fvm) between the optocoupler and gate for each scr. I'm getting the desired waveform.
Thank you for your responses. Now I understand the gate current. I'm using them in series is because I'm trying to achieve a cycloconverter and I need current flow just in this section, I send pulses to specific scr in order to get a desired waveform. 30hz, 20hz, 15hz.
Hello everybody,
I'm designing a firing circuit for an SCR TIC106D, the datasheet shows a maximum Igt current of 200uA. But if I simulate it in proteus it doesn´t work as expected. Here are some screenshots of my design.
I still don´t have the real parts, so I can´t test it. Therefore I was...
