The MQ Power Advantage
It's All About Performance

There are several features of MQ Power Whisperwatt™ generators that set them apart from the competition...

Open Delta Windings

Our patented, Open Delta Windings provides a consistent voltage input reference for the voltage regulator, non-linear load protection, and provides 300% short-circuit support to aid in clearing fault conditions.

Open Delta Windings
Seperate Exciter Winding

This system provides Separately Derived Excitation voltage for the generator, similar to a Permanent Magnet Generator (PMG)

The voltage regulator is powered by a separate excitation winding which provides dedicated input voltage to the voltage regulator allowing it to more precisely control voltage output

The Open Delta Windings provide a high degree of immunity from non-linear loads, such as X-Ray machines, MRI’s, and other SCR loads (UPS systems) to maintain proper voltage output during operation of these loads

In the event of a three-phase, bolted fault - which is the highest magnitude fault current that could result if the line, neutral or ground conductors become solidly connected together - the generator output voltage will drop to zero

The separate exciter will continue to deliver precise input power to the voltage regulator providing excitation necessary to aid in clearing the fault and help prevent the entire load from being taken offline

Main Benefits of a Separate Exciter Winding include:

  • Provides a consistent voltage input reference for the voltage regulator and is un-affected by non-linear loads
  • Provides better motor starting and full load performance
  • Provides 300% short-circuit support for 10 seconds to aid in clearing fault conditions

Shunt Excitation Systems

Many MQ Power competitors use the Shunt Excitation System, an alternative method of powering the voltage regulator which receives its power from the output of the generator. This is commonly referred to as self-excited regulation.

Shunt Excitation Systems are not immune from non-linear loads (electrical loads that distorts the voltage wave form from the generator, such as large motors, x-ray machines, MRI machines, etc.)

They can also result in poor voltage regulation and less performance during motor starting and full load operations


Denyo Automatic Voltage Regulator (AVR)
A Unique MQ Power Feature

During normal loading, power to the voltage regulator is provided by a parallel connection, where the three phases of voltage input to the AVR are rectified and become the excitation current for the exciter (separately-derived excitation). This is unique to MQ Power.

During heavy motor starting, or in the event of a short circuit, the AVR switches the open delta configuration to a series connection. This provides higher excitation to the exciter (voltage boost) and better voltage response during application of heavy loads.
