Hello,
I attach a fragment of circuit found in the internet. I'm trying to design my own circuit similar to that. That design corresponds to a dc motor control board. As you see in the picture, there is the AC input, goes through a relay contact and feed the rectifier. How do I choose my own relay and rectifier? Let's say that the bridge rectifier output goes to the capacitors and feed a 130V, 4HP motor. Do I calculate the max current that my bridge and relay should stand according to the motor ratings, right? If I'm going to feed another part of the circuit with the same DC bus, I need to take into account all of the currents which I expect that will come from out of the bridge.
