The inverter module is the module that contains the SGCT power device
necessary for producing the motor voltages and currents. There are three
inverter modules in each drive; the number of SGCTs per module depends
on the voltage rating of the motor. To understand a module, a description
of a single SGCT and its peripheral equipment is all that is required.

Component Definition and Maintenance
The SGCT circuit board is sensitive to static
charges. It is important that these boards should
not be handled without proper grounding.
Some circuit boards can be destroyed by static
charges. Use of damaged circuit boards may
also damage related components. A grounding
wrist strap is recommended for handling
sensitive circuit boards.
