DESCRIPTION

Mechanical Arrangement and Options

The variable-voltage, variable-frequency power
inverters of the GV3000/SE series are ready for
installation and are available in different sizes
with output currents in the range 2 to 360 Amps.
They are designed to drive induction motors at
variable speeds using PWM technology.
The protective enclosure contains the Power
Module and the Control Unit with the Keypad.
Figure 2-1 shows the block diagram of the
inverter with specified options.

1 Line Filter

The built-in option RFI- or HF-Filter limits
high frequency emission to permitted
values. See Selection Tables 2-8,
Chapter 5 and Appendix A.
2 Braking Unit (built-in on types 003-030,
039/044, option on 038/043, 058 - 240),
switches during motor regeneration the
externally mounted (user supplied)
braking resistors to the DC-bus and
prevents by that bus overvoltage.
3 DC-Bus Terminals
(option on type 038/043 and >058) e.g.
for connection of external braking unit.
On types >AC180 additional DC-Bus
bus-bar connections (145,147) are
available.
4 Diode Bridge (on types 003-170).
or Six Pulse Rectifier Bridge
controlled by the pulse firing card FPS
(on types 180-360).

5 Power semiconductors
IGBT (insulated gate bi-polar transistors)
or IPM (Intelligent Power Modules).
These are switched on and off by the
gate drivers to provide phases U,V,W to

the motor.
6 Gate Driver and Power Supply Card
Interface between the power modules
IGBT and power interface card.
