Advantages of a medium voltage variable
frequency system
Key benefits
• Peak power density
• High reliability and availability
• Power scalability with customizable
options 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
– Visor Connect supports warranty
with remote real-time support
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 to
double 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
Industry sector Applications
Oil and gas eLNG trains, injection compressors and pumps, gas
storage, multiphase pumps, pipeline compressors
Marine Cruise ships, LNG carriers, offshore drilling vessels,
research vessels, megayachts, merchant vessels,
navy support vessels
General and
heavy industry
Metal rolling mills, test benches, grinders, water pumps,
mine winders, crushers, ID fans, FD fans, wind turbines,
static frequency converters, boiler feed pump, power
quality systems
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.
