5.7.4 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.
5.7.5 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.
5.7.6 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.
