VLT® 7000 Booster

■

Control principle

A frequency converter rectifies AC voltage from

mains into DC voltage, after which this DC

voltage is converted into a AC current with a

variable amplitude and frequency.

The motor is thus supplied with variable voltage and

frequency, which enables infinitely variable speed

control of three-phased, standard AC motors.

1. Mains voltage

3 x 380 - 460 V AC, 50 / 60 Hz.

2. Rectifier

A three-phase rectifier bridge that rectifies AC

current into DC current.

3. Intermediate circuit

DC voltage = 1.35 x mains voltage [V].

4. Intermediate circuit coils

Even out the intermediate circuit voltage and reduce

the harmonic current feedback to the mains supply.

5. Intermediate circuit capacitors

Even out the intermediate circuit voltage.

6. Inverter

Converts DC voltage into variable AC voltage

with a variable frequency.

7. Motor voltage

Variable AC voltage, 0-100% of mains supply voltage.

8. Control card

This is where to find the computer that controls

the inverter which generates the pulse pattern by

which the DC voltage is converted into variable

AC voltage with a variable frequency.
