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 through the output con- tactor, which is activated by the printed circuit board, to the output terminals. If AC output is selected, then the current path is from the stator weld winding through the reactor, range switch, polarity switch and output contactor to the output terminals. If a DC out- put 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 out- put is filtered. The filtered DC current path is through the polarity switch and output contactor and then on to the output terminals.

If a CV (constant voltage) mode is desired, the reactor is passed by. The range switch applies a lower AC voltage to the rectifier bridge. The DC output of the bridge is filtered and “stiffened” by the capacitors. This lower but “stiffer” DC output is passed through the choke, polarity switch, and contactor and then on to the output terminals.
