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.
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.
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.

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.

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.
