Maximizes Uptime Through Redundancy and ProToPS™ Process Control

Reliability

The reliability of the Perfect Harmony 

drive is second to none due to Siemens’

common-sense approach to component

selection and design. Traction grade

insulated Gate Bipolar Transistors (IGBTs)

form the backbone of the Perfect Harmony

drive. Built-in high volumes and serving

as a proven power device across the

industrial power control industry, IGBT

technology has been in existence for

more than a decade. The stability and

availability of IGBTs give you reliable,

long-term, life-cycle confidence. But

that’s just the start of our forwardthinking design.

Advanced Cell Bypass

The Perfect Harmony is engineered 

to withstand failures that would overwhelm conventional drives because

we’ve added redundancy options into

the system. Our patented, cell-based

configuration maximizes uptime and

simplifies modifications. Through a

redundant bypass control that is

completely separated from each power

cell, the Perfect Harmony ensures

automatic bypass of a failed power 

cell in 250 milliseconds (less than 1/4 

of a second).

Another feature that bolsters the Perfect

Harmony’s reliability is its control strategy.

Our Process Tolerant Protection Strategy

(ProToPS™) is a groundbreaking process

control system available exclusively from

Siemens. Instead of tripping the drive and

automatically shutting down the system

due to a malfunction, ProToPS provides 

a hierarchical system of warnings. This 

control strategy allows time to evaluate 

the situation and respond appropriately

to avoid a system shutdown. ProToPS has

proved invaluable for many of our Perfect

Harmony customers, including strategic

power plants, refineries, water and

wastewater facilities, and process plants.

Factory System Test

Upon delivery, you can be confident 

that the Perfect Harmony will get your

process running because we have the

ability to test every product as a

complete system at full load. At our

factory, we test every transformer and

power converter together so that any

imperfections can be identified and

corrected before the product is shipped.

In addition, factory testing allows

accurate efficiency measurements. We

also verify sequence of operation and

protection to ensure that the Perfect

Harmony system matches your needs.

Protecting Process Quality

If a power cell is bypassed, there is minimal degradation of the motor’s

output power quality, as the Perfect Harmony’s advanced power cell 

bypass system ensures that your process is uninterrupted.

Trusted in the Most Demanding Applications

The Perfect Harmony is regularly applied 

by the most reliability and quality 

conscious industries and their most

demanding applications.

Oil and Gas

ESP's – offshore and onshore for powering

electrical submersible pumps at cable 

lengths up 35 km (22 miles) without

complicated output filters.

High Speed Compressors - process critical

high speed applications for liquefied 

natural gas and refineries consistently 

choose the Perfect Harmony because it

delivers sinusoidal power at output

frequencies of 330 hertz and beyond

making these systems less complicated,

more efficient and lowering their life 

cycle maintenance.

Power Generation

Induced and forced draft boiler fans –

when the power has to be delivered 

the Perfect Harmony has been the

overwhelming choice of the U.S. power

generation market because of the

Siemens’ engineering expertise and 

the remarkable reliability that the each

and every installation has shown.

Water

In more than 20 countries, the Perfect

Harmony drive is the medium voltage

drive of choice for all types of critical

clean water and wastewater pumping

applications.

Adding to the versatility of the Perfect

Harmony drive, it is available with 

forced-air-cooling (bottom) or selfcontained, closed-loop, water-cooling

(top). Redundant pumps are standard 

on water-cooled units. Redundant

blowers are a standard option for

air-cooled units. The multi-cell design

allows quick rack in/out of power cells,

making maintenance of the Perfect

Harmony very quick and simple. A

hydraulic “cell lifter cart” is an option

for larger cell designs.
