Interface Board
This circuit board takes current transformer signals plus line-side and load-
side voltage feedback signals from the voltage sensing board and passes
them to the SMC-Flex for processing. The control module produces gating
signals for the SCRs, which are received on the interface board, and used
to drive fibre-optic transmitters. The gating signals are sent to the gate-driver
circuit board via fibre-optic cables. The interface board also receives
temperature feedback from the gate-driver board via fibre-optic cable(s).
If the heatsink temperature rises above a set value, a signal is sent to the
SMC-Flex to stop gating the SCRs and initiate a temperature fault.
For a detailed layout of this circuit board, refer to Figure 3.2 on page 3-6.
