Re: [CAD_CAM_EDM_DRO] regulated power supplies???????????

I think it would be more accurate to say that if you are using a chopper
type motor driver there is no NEED to regulate the power supply, because the
driver does it. The PWM motor driver is essentially a current regulator,
whereas most conventional switching power supplies are voltage regulated.
Using a voltage regulated power supply with a current regulated driver is
just overkill, but not inherently bad, so long as you have enough of a
capacitor to buffer the switching supply from the current spikes induced by
the driver's chopper. Clear as mud.
