Frequency Converters


3 Phase Power Frequency Including 50 Hz, 60 Hz and 400 Hz and others.

Power Frequency refers to how many times the wave form will repeat the cycle per second.

The most common utility frequency is the frequency at which alternating current (AC) is transmitted from a utility company power plant to the end user In most parts of the Americas (North and South), it is typically 60 Hz, and in most parts of the rest of the world it is typically 50 Hz.  

Most places that use the 50 Hz frequency tend to use 220/230 voltage, and those that use 60 Hz tend to use 110/120 V.

Other utility frequencies are used for specialized purposes and in other countries as a standard. The countries Germany, Austria, and Switzerland use a traction power network for railways, distributing single-phase AC at 16.7 Hz. A frequency of 25 Hz was used for the German railway Mariazeller Bahn and some railway systems in New York and Pennsylvania (Amtrak) in the USA.

Frequencies as high as 400 Hz are used in aerospace and some special-purpose computer power supplies and hand-held machine tools. Such high frequencies cannot be economically transmitted long distances, so 400 Hz power systems are usually confined to the building or vehicle.

Power Frequency (Hz) Can Be Changed with a Frequency Converter

Frequency Converters, also known as Motor Generator Sets (MG Sets), are used for converting either 50 Hz, 60 Hz, or 400 Hz, utility line power to 50 Hz, 60 Hz or 400 Hz power to run equipment. In addition to this some frequency converter manufacturer's, namely TEMCo, Frequency Converter MG Sets also offer line isolation, harmonic cancellation, power factor correction, phase conversion, voltage conversion with balanced, smooth, controlled power output. Typical applications include AC variable speed drives, inverters, computers and computer controlled equipment, deep well pumps, industrial machinery, ships, aircraft, military computers and many more.  Click here to read more about Frequency Converters.

3 Phase Power Wave Form
One voltage cycle of a 3-phase system, labeled 0 to 360 ( 2 π radians) along the time axis. The plotted line represents the variation of instantaneous voltage (or current) with respect to time. This cycle will repeat 50 (50Hz) or 60 (60Hz) times per second, depending on the power system frequency.

Common Frequency Converter Configurations Include:

50 Hz or 60 Hz Input
50 Hz, 60 Hz, or 400 Hz Output
120 Volts through 600 Volts Input
120 Volts through 600 Volts Output
1 or 3 phase Input
1 or 3 phase Output
6 kW through 200 kW

Variable Frequency Drives Used To Control Motor Speed:

Variable Frequency Drives and Soft Start Drives are not actually used to change power frequency, but instead are used to control motor speed for applications that need a motor to speed up or slow down.  If you need to change power frequency see above for Frequency Converters. 
 

3 Phase Power Is More Efficient Than Single Phase

Three phase electricity powers large industrial loads more efficiently than single-phase electricity. When single-phase electricity is needed, It is available between any two phases of a three-phase system, or in some systems , between one of the phases and ground. By the use of three conductors a 3 phase system can provide 173% more power than the two conductors of a single-phase system. Three-phase power allows heavy duty industrial equipment to operate more smoothly and efficiently. 3 phase power can be transmitted over long distances with smaller conductor size.
