Three Phase
Electrical Power Converter
Often the advantages of three-phase power for motors and other 3-phase equipment make it worthwhile to convert single-phase to three-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. 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 for motor speed control (VFDS). 3-phase motors drive some locomotives with 3 phase converters converted from the incoming supply of either DC or 1 phase AC. The two main types of 1 phase to 3 phase converters are Rotary Phase Converters and Static Phase Converter s. Read below for more about 3_phase converters .
3 Phase Converter
Types and Comparison
There is a big difference between phase
converter types available on the market today. Most 3 phase
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 Converter Types and Comparison
Good old fashioned research will help guide you to make sure that you are able to get the proper product to give you balanced 3 phase power. The US Phase Converter Standards Organization has some excellent guides to help choose the appropriate technology for your need comparing them side by side. Check out their Phase Converter Type Comparison Chart to read about the strengths and weaknesses of each 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 Phase Converters
the most common type of phase converter is the Rotary Phase Converter. Not all Rotary Phase Converters are the same. Many just convert single-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 Phase Converters. A few other companies called this type of 3-phase generating rotary phase converter a motor generator set.
Static Phase 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. Read more about Static Phase Converters here.
