6.4) SWITCHING FEEDER
The switching feeder is provided by a DC/DC Flyback converter.
The Flyback stage is supplied by the +35Vdc voltage present on the
BUS and makes it possible to obtain the -1Vdc, +1Vdc, +15Vdc
and +5Vdc voltages required to supply the various boards.
The electronic switch of the feeder is a MOSFET. The functional
wiring diagram of a multi-output DC/DC Flyback converter is illu-
strated in the figure below.
The welding control logic present on board 15.14.43 and the
power stage control logic present on board 15.14.44 monitor the
state of the equipment and inform the operator via the LEDs present
on the front panel.
