phase Medium Voltage supply to Medium Voltage DC, which is then fed to the In-
verter.
DC Bus Bar
The two DC Bus Bars are in the Cell Section of the Inverter. They supply the DC bus
to the Power Cells.
Disconnect Switch
A Disconnect Switch is a mechanical switch. There may be Disconnect Switches on
the input and on the output of the drive. They may be opened to isolate the drive or
motor from sources of power for maintenance.
Dual Diode Module
A Dual Diode Module is a package that contains two high-current, high-voltage di-
odes in series, three terminals, and a metal heat transfer plate. Each Rectifier Mod-
ule contains three Dual Diode Modules mounted on a heatsink. They are connected
in a bridge circuit to implement a full-wave, three-phase rectifier.
Ethernet Switch
An Ethernet Switch is a network device with multiple ports. It is used to connected
multiple host devices to the same network. It learns the IP address of each host con-
nected to a port. It reduces messages received by each host by only sending traffic
to a port if the message’s target IP address is attached to that port.
FOB
Fiber Optic Board.
See Power FOB.
HMI
The Human Machine Interface is a touch-sensitive, graphical display. It is mounted
in the door of the Low Voltage Section of the Inverter. It provides real-time status of
the drive. It may be used to configure drive parameters, and view the event log.
IGBT
Insulated Gate Bipolar Transistors are the power semiconductor switching devices in
the Power Cells.
Inner Air Filter
An Inner Air Filter is the second stage of a two-stage air filter. It is located inside the
enclosure.
Inverter
The Inverter is one of the major components of the drive. It is an enclosure that
houses the Power Cells, the Card Cage, and the HMI. It performs multi-level, pulse
width modulation to convert Medium Voltage DC to three-phase Medium Voltage,
which is then fed to the motor.
Inverter IO
The Inverter IO is a set of analog and digital inputs and outputs located in the Low
Voltage Section of the Inverter.
Some of the IO points are reserved for use by components internal to the Inverter.
Other IO points are configurable and may be used to interface to the plant.
