I have been trying to understand this circuit, but i do not know how rectification occurs at the output or R1. C1 is capable of voltages up to 63V and C2 is capable of voltages up tp 50V. I used Circuit Maker and actual sine wave to look at signals at different nodes. Somewhere in the circuit AC is switched to DC. I just do not know where. I know C2 performs the full wave rectifcation, but where is the half wave rectification. Also, I think D1 is to prevent signal loss, but I am not sure. Please help me understand why R3, R2 and C1 is needed at the gate of the SCR. Once the gate is triggered the SCR will conduct, correct. I am doing a Co-Op. This is just portion of the overall circuit. There are 3 phase generators to this circuit. They all look like this. I figure if i understand this circuit I can understand the rest.
Please Help
