3 Phase Electrical Power Converter
Often the advantages of three-phase power for motors and other 3 phase equipment make it worthwhile to use single-phase to generate 3 phase power.  Rural business or farm properties, and urban residential area power consumers, may not have access to a 3 phase supply, or may not want to pay for the extra cost of a 3 phase service, but may still wish to use three-phase equipment. Even in urban areas where 3 phase power is readily available many businesses with expensive or sensitive equipment would rather generate their own 3 phase power with a 3 phase generating rotary phase converter.  Some of such 3 phase converters may also allow the frequency (see also frequency converters) to be varied allowing for different equipment frequency requirements (50Hz, 60Hz, 400Hz, etc.) and also for motor speed control (VFDs).  Some locomotives are driven by 3-phase motors with 3 phase converters converting the incoming supply power of either DC or single-phase AC.   The two main types of 1 phase to 3 phase power converters are Rotary Phase Converters and Static Phase Converters.  There is a very distinct difference between these phase power converter types.  Click here to read more about 3 phase power converters.

 

3 Phase Power Generating Phase Converter
There is a very important difference between 3 phase converter types available on the market today.  Most 3 phase power converters sold by companies today do not produce actual balanced 3 phase power.  This is why is very important to select a 3 phase generating phase converter which will run on single phase power and generate true balanced smooth 3 phase power.  Below is a comparison of several technologies available today.

3 Phase Power Converter Types and Comparison

Let our research and that of the US Phase Converter Standards Organization help guide you to get the proper product to give you balanced 3 phase power.  The US Phase Converter Standards Organization has some useful phase converter selection and technology guides to help choose the appropriate technology for your need.  These 3 phase power converter guides compare the different technologies side by side for easy understanding.  Check out their Phase Converter Type Comparison Chart to read about the strengths and weaknesses of each 3 phase converter type side by side with their ratings on quality, durability, safety, and 3 phase power quality produced.  They also offer a useful 3 Phase Converter Resources page.

Rotary 3 Phase Power Converters

The most common type of 3 phase power converter is the Rotary Phase Converter.  Not all Rotary Phase Converters are the same.  Many just convert 1 phase power into unbalanced 3 phase power, while the best kind that we were able to find will actually generate true balanced 3 phase power.  This is the best kind to use.  There were only a few companies who manufacture this type with the most notable brand being TEMCo 3 Phase Converters.  A second quality brand also recommended by the US Phase Converter Standards Organization is the popular Ace Phase Converter brand.  A few other companies called this type of 3 phase generating rotary phase converter a motor generator set.  

Static 3 Phase Power Converters

The next most common type of phase converter is called a Static Phase Converter.  These can only be used on 3 phase motor loads.  These units only generate a 3rd leg of power during start up but then turn off leaving motors to run simply on 2 out of 3 of their windings.  This can damage some types of 3 phase motor loads by over heating the motor and burning it out when it is put under its full load.  Many times a load has 3 phase circuitry and not simply a motor load so it will not even work with a static phase converter.  There are useful some very useful technology charts which answer the questions about what is a Static Phase Converter.  Read more about Static Phase Converters here.

CNC 3 Phase Power Converters

The last common type is the CNC Phase Converters. These are simply a Rotary Phase Converter with more balanced 3 phase output manufactured to provide 3 phase power to sensitive computers that are a part of CNC machines.  The most popular and recommended CNC Phase Converter is the Series 7000 CNC Pro Rotary Phase Converter.  

3 Phase Loads on 1 Phase Power

The most effective and efficient way to run 3 phase equipment on 1 phase power is with one of the above 3 Phase Power Rotary Phase Converters.  This will not only give you the 3 phase power solution but it will also, with the correct technology choice, give you better than utility supplied 3 phase power.

1 Phase Loads on 3 Phase Power

1-phase loads may be connected to a three-phase system in two different ways.  This can be done either by connecting across two live conductors (phase-to-phase connection), or by connecting between a phase conductor and the system neutral, which is either connected to the center of the Y (star) secondary winding of the supply transformer, or is connected to the center winding of a delta transformer (High Leg Delta system). Single-phase loads should be distributed evenly between the phases of the 3 phase system for efficient use of the supply conductors and supply transformer.   Click here to read more about connecting a 1 phase load to a 3 phase power supply line.
