Re: [CAD_CAM_EDM_DRO] Separate bridge rectifiers and transofromers

Hi Scott,
You can have 3 separate power supplies. However it is better to have one
big supply. A single big supply will cope better with acceleration
surges and will absorb deceleration spikes better.

Another option is to use 3 transformers and rectifiers feeding one
smoothing capacitor. It is potentially dangerous to connect transformer
outputs directly together but the rectifiers will effectively stop the
transformers from fighting each other.
