5.7.3 Amplifier Boards
The Amplifier boards are each attached to a heat sink and stacked on top of
each other at the top portion of the power module enclosure. Sets of two
boards are held together by a bracket which screws into the back wall of the
power module enclosure. Power to each amplifier board is supplied from the
PFC section through a set of DC bus bars. Each amplifier board connects to the
modulator board via a small ribbon cable. Each Amplifier board has four
outputs (A+. A-, B+ and B-). These four outputs connect to a set of Inductor
boards using stranded wires with Anderson style connectors. The connection
between the Amplifier boards and the Inductor boards is specific and should not
be reversed or damage could result. The output wire connectors of each
amplifier board are color coded to help identify the correct connections. The
connections between the Modulator board and the Amplifier boards are one to
one. (Connectors line up with amplifier boards).
The layout of the Amplifier board is shown in Figure 5-5.
