OUTPUT BRIDGE, CHOKE,
POLARITY SWITCH, AND OUTPUT
TERMINALS
The AC voltage developed in the stator weld winding
is delivered, through the reactor and range switch, to
the output bridge and polarity switch. Depending
upon the setting of the polarity switch, either AC volt-
age or DC voltage is delivered to the output terminals.
If AC output is selected, then the current path is from
the stator weld winding through the reactor, range
switch and polarity switch to the output terminals. If a
DC output is called for then the current path is through
the Output Bridge, where the AC voltage is rectified to
a DC voltage, and then to the choke, where the DC
output is filtered. The filtered DC current path is
through the Polarity Switch and on to the Output
Terminals.
