Filter Boards
A set of two identical inductor boards is located behind the Modulator board and next to the four amplifier
boards. One filter board handles the "A" output, the other handles the "B" output. In addition to the
filtering function performed by these boards, the inductor boards also contain current sensors that are used
in the feedback loop of the amplifier. The output of these current sensors is routed to the modulator board
to regulate current sharing and peak current limiting.
6.7.5
Fan Supply Board
The Fan Supply board is located in the wind tunnel of the PFC section at the bottom of the power module.
This board provides variable speed control for the dual fans of the power module. Fan speed is a function
of the load current sensed. This provides for lower levels of audible noise during minimal load conditions.
6.7.6
Output Snubber Board
A small output snubber board is attached to the output terminals of each power module. This snubber
provides the required operating stability of the amplifiers.
