Default North London Line AC/DC question

Modern EMUs use three phase traction motors and both AC and DC line
voltages need to be converted for the three phase power electronics.

My understanding is that when you have three-phase AC motors, all
power sources (AC, DC and diesel) are converted to DC at some point,
before being fed into the electronics that create the three-phase for
the motors. So in theory they should all be interchangeable, but I
doubt it's that simple.
