What Does No Break Power Transfer (NBPT) Mean?

The Value of Fault Codes

Every once in a while, something goes wrong. Many things, like a flat tire, are easy to diagnose. “Sounded like BANG Whomp, Whomp, Whomp. Looks like a flat tire, must be a flat tire. “ Other things are more complex. Let’s stick with tires for the moment. Newer vehicles come with pressure sensors in the […]

What is the difference between Analog and Digital?

What Are The Benefits Of A Simple Inverter Model?

Last time, I presented an example of a simple 3-phase inverter. An analogy was made to a 3-cylinder engine. (One cylinder per phase) Using Pulse Width Modulation (PWM), each phase can appear to be more than the simple on/off which was shown in the timing chart. By switching on and off very quickly, a series […]

What Is A 3-Phase Inverter?

Many times I’m asked to explain a technical statement to a person who is either non-technical or from a different branch of technology. One such question stemmed from a general comment regarding inverter sizing. The inverter is the group of switching devices that convert DC into AC. In the next two figures, DC on the […]

What Is A Power Inverter?

In discussions on solid-state frequency converters, mention was made of an inverter used to create the 400 Hz output frequency. Here, we will describe in layman’s terms how an inverter works. First, we begin with a direct current (DC) source of power. This can be a battery or the output of an AC to DC […]

Benefits of Solid-State Frequency Converters

Last time, we discussed why the utilities supply 50 or 60 cycle (Hz) power and the aviation industry operates on 400 Hz power. Obviously, the two systems are not compatible. 400 Hz is 6-2/3 times faster than 60 Hz and 8 times faster than 50 Hz. The speed of motors (and clocks) would be multiplied […]

Why the Aviation Industry Operates on 400 Hz Power

The idea of making electricity useful for commercial lighting and motors initiated an argument. One side wanted direct current (DC). One wire will always be positive (+) and the other wire is always negative (-). The other side supported alternating current (AC). In this system, the voltage is constantly moving between positive and negative. The […]


Supplying 400 Hz Ground Power to the World’s Largest Marine Corps Facility Recently, FCX commissioned 16 solid-state frequency converters in the U.S. Marine Corps’ newest MV-22 Osprey Hangar located at MCAS New River in North Carolina.

Grand Bahama Shipyard

In 2008, a large floating dry dock – containing motor loads for cranes, capstans, ballast pumps and fire pumps – was transported to the Grand Bahama Shipyard. The dry dock required 50 Hz power, while the Bahamas utilizes 60 Hz power.

To supply the 50 Hz power needed for the dry dock, two 1000 KVA Caterpillar diesel generators were required. A solid-state frequency converter running off the utility solved this problem.
