How Efficient is a Phase Converter?

 

Efficiency of Phase Converters
Phase converters are extremely efficient, usually around 80 to 95 per cent of the time.  Losses are usually less than 15 per cent and usually under 10 per cent. One thing to keep in mind, that each kind of phase converter has a different efficient level. A static-phase converter does not consume much power in themselves, because they are very simple devices that have no moving parts. However, the motor you are operating will lose efficiency because of its very poorly balanced power.  The motor is severely de-rated, and if the motor is asked to perform more work than half of its capacity, it could overheat and cause
permanent damage.

Rotary-phase converters do a better job of supplying a balanced voltage load but still has difficulty producing highly balanced power. Rotary-phase converters must always be sized larger than the power needed to run the equipment in order to handle motor starting currents. It is common for converters to be two to three times the size of the operated load for demanding applications. The rotary converter is also a consumer of power itself.  Oversized rotary converters may waste as much as 30 per cent of the power they draw.

VFDs and digital-phase converters are very efficient because they have no moving parts, and they supply a perfectly balanced power source. At first glance, a VFD offers the best efficiency because it generates less heat internally.  However, the harmonics generated on the input and output causes efficiency lost through generation of heat in the load and in the utility transformer.  So the VFD causes efficiency loss at other points in the system. The digital-phase converters have filtering systems for both the input current and output voltage to remove harmonic distortion that can affect the load and the utility transformer.  Removing these harmonics results in heat losses within the converter and, in turn, loses efficiency. In overall efficiency, the digital converter is probably the most efficient, because it creates one voltage.  The VFD creates all three voltages leading to more heat loss in the motor windings

The Website to get all your Phase Converter Questions Answered

 

Welcome to PhaseConverterFAQ.Org Website, which is absolutely the best site to get up-to-date information and all your questions answered about phase converters.

This site was established to share resources and answer questions about phase converters, their applications and how they work. With these articles, you will obtain basic knowledge about phase converters enabling you to make a sound judgment in choosing the right phase converter for your application.

Technology has come along way since the first-phase converter was invented almost 100 years ago with the static-phase converter. Now there are hundreds of companies, large and small, manufacturing phase converters, and you will find a wide array of prices, power quality, voltage, efficiency and versatility. Before buying your phase converter, always check on your manufacturer to make sure you get a quality phase converter that will offer you years of service. Make sure they stand behind their products and check on their customer service.  With this site, we will help you better understand these matters and make it easier to select the right phase converter that best suits your operational requirements.

Phase converters, in recent years, have expanded dramatically in industrial and commercial applications. This trend is driven by economic factors including utility charges for expending three-phase lines, construction delays in obtaining  new service, and limited availability of single-phase equipment. Utilities are under great pressure from regulatory agencies to justify capital investments before granting rate increases. They respond by scrutinizing requests for service extensions. If the investment in expending a customer line can't be paid back fast enough through energy revenues, the utility will charge the customer for the new service.  Charges vary according to terrain and the complexity of the change, but a common average is $50,000. So even in short distances, it is prohibitive for a small businesses.

The potential savings by using a phase converter can be breathtaking compared to alternative utility costs. Still, the use of phase converters remain a mystery to many who could benefit most. Chief reasons are widespread anecdotal accounts of field problems and other misunderstandings of applications. Understanding how converters work and having a quality phase converter can save you money and headaches.

This site covers information and answers from the basics, "Why would I use a phase converter?"  Our site provides more specific details about the different applications. We offer detailed information on different types of phase converters including answers on what is a rotary-phase converter, and what applications it is used for.    

Our site answers questions regarding how efficient are phase converters, how many motors can operate on a single converter, and do phase converters require any adjustments during operation. We cover information on applications, operating and installing converters and any general information you may need.

We hope our information will be useful for the first-time user of a phase converter.  In addition, we hope we can also benefit the more experienced user with better resources and the latest state-of-the-art knowledge of phase converters.  Our goal is to create a one-stop resource for your phase converter needs and questions. We feel that after visiting our site, you will be an informed consumer, and the detailed information will help you in making the correct choices concerning your phase converter.

Other Helpful Phase Converter Resources:

When you need information from a
rotary-phase converter or static-phase converter manufacturer, we recommend TEMCo Phase Converters or ACE Phase Converters as they are the most popular and recommended quality product on the market.  The TEMCo brand of CNC phase converters have the highest quality reputation of any company supplying the voltage sensitive CNC market.  Their section on three-phase loads can be handy in determining if your application will have a higher draw of power at startup.

Since the purpose of a phase converter is to generate three-phase power from single phase, the Three-Phase Power Resource Site is an excellent resource for a variety of information from wire color codes to machinery applications, and the history of three-phase power.  They also have a handy section on three-phase converters.

If you need three-phase power from single-phase and you are not sure what type of phase converter would best meet your needs, then the U.S. Phase Converter Standards' Web Site is very handy.  It has some useful research and comparison charts that give more information into the following types: digital-phase converters, which are controlled by electronics; VFD-phase converters, which use a variable frequency drive to change the frequency and phase; build-your-own phase converters, which are homemade or self-built plan types; phase converter plans with the warnings about the types and also the dangers (and possible waste of time)' phase inverters, which invert the sign wave and are often a VFD; CNC-phase converters for computer controlled mills and other devices with sensitive electronics; rotary-phase converters, which are the most reliable type when acquired from a reputable manufacturer; and static-phase converters, which are also electronic but have a tendency to damage the equipment they were meant to run (rotary-phase converters are usually a much better choice).  In addition to this, they also have some useful phase converter resources.

When setting up a phase converter, it is often necessary to change not only the phase but also the voltage.  The voltage can be changed with a three-phase transformer (sometimes referred to as a voltage converter).  The three most popular transformer brands are Hammond, TEMCo and Acme Transformers.  If there is no reliable source of power, than it may be an alternative to use a three-phase generator.  Frequency is most reliably changed with a Motor Generator Set that is built as a specialized frequency converter.

Hopefully, the above resources are helpful for you.  We are here to serve the electrical community and offer handy information to electricians and others looking for more information and choices for their three-phase electrical power needs.
