GE MV7000 Reliable, high performance medium voltage drive

Cutting-edge power electronics technology and decades of process

expertise come together in the MV7000 — a world-class water-cooled

medium voltage drive suitable for a wide range of power conversion

applications. Easy to install and maintain, the drive offers high reliability

and availability and helps increase the uptime of critical processes.

The MV7000 provides a flexible approach to achieve a customized

solution across different applications.

With the MV7000 our power conversion expertise helps increase

operating efficiency, power availability, plant throughput, operational

precision, and process yield. We are helping our customers meet the

demands and opportunities of the new electric age.

Benefits:

• Peak power density — our drive can deliver up to 15 MW with just

18 IGBTs, which is equivalent to a power density of 1.5 MVA/m3

• High reliability and availability — over 10 million hours in operation

across an installed base of over 8.5 GW

• Power scalability with à la carte option packaging that can be

adapted to a wide range of applications

• A full family of drives — GE is your one-stop provider with a

wide portfolio of drives

Advantages of a medium voltage variable frequency system

Reliability & availability 

The higher reliability and lower maintenance needs of a variable

speed drive system compared to gearboxes and hydraulic couplings

result in lower lifecycle cost.

Saving energy, caring for the environment

In today’s world more than ever, energy saved is energy produced.

For a variety of loads, from water pumps to gas compressors, variable

speed control offers the best way to capture energy savings.

Precise power delivery

In many applications, the superiority of electrical control simply cannot

be matched by mechanical systems.

Precise control of power means better outcomes, from the flatness of a steel

sheet to the accuracy of offshore Oil & Gas exploration.

MV7000 — Enhanced technology Key benefits

• Peak power density

• High reliability and availability

• Power scalability with customizable ptions featuring:

–  Low harmonics without additional equipment

–  Four quadrant operation for regenerative applications

–  Transformerless design for compactness

–  Common DC bus system for energy savings

–  High performance process control

and advice

• Front access maintenance

Best-in-class power density

The phase power stack is the main modular building block of the three

level inverter.

•  Compact enclosures thanks todouble sided cooling of the IGBTs

•  Just 18 IGBTs at 3.3 kV can deliver 15 MW

•  Control hardware mounted on a slide in/out frame

•  Simplified cooling system architecture and gate drive power supply topology

• Fuseless design

High reliability and availability

The MV7000 is a great example of a design philosophy based on minimizing

component count while retaining peak performance.

Press-pack IGBT (PPI) power devices enable:

• The capability to limit overcurrent with safe turn-off under all operating

and failure conditions

• Case rupture-free due to pressed contacts and no-wire bonding

• N+1 series redundancy thanks to the capability of PPI for continuous

conduction under failure mode

• Long life expectancy even under load cycling

• Effective performance even at low motor frequency operation
