Frequency Converters

Frequency converter, also known as a frequency changer, is a device that takes incoming power, normally 50 or 60 Hz and converts it to 400 Hz output power. Different types of power frequency converters exist, specifically, there are both rotary frequency converters and solid state frequency converters. Rotary frequency converters use electrical energy to drive a motor. Solid state frequency converters take incoming alternating current (AC) and converts it to direct current (DC).
What is the purpose of a power frequency converter for commercial utility?

Standard commercial utility power is alternating current (AC) power. AC refers to the number of cycles per second (‘hertz” or Hz) that the power fluctuates, positive and negative, around a neutral datum. Two standards exist in the world, 50 hertz and 60 hertz. 50 Hz is prevalent in Europe, Asia and Africa, while 60 Hz is the standard in most of North America and some random countries (Brazil, Saudi Arabia, South Korea) around the world.

There is no inherent advantage to one frequency over another frequency. But there can be significant disadvantages. Problems occur when the load being powered is sensitive to the input power frequency. For example, motors spin at a multiple of the power frequency. Thus, a 60 Hz motor will spin at 1800 or 3600 RPM. However, when 50 Hz power is applied, the RPM is 1500 or 3000 RPM. Machines tend to be speed sensitive, so the power to run them must correspond to the design RPM intended. Thus, a typical piece of European machinery needs 50 Hz input, and if it runs in the United States, a 60-to-50 Hz converter is required to convert the available60 Hz power to 50 Hz. The same applies vice versa to convert 50 Hz power to 60 Hz. While standard power ratings and capacities exist for frequency converters, our converters operate over a range of voltages from 100V to 600V. The most commonly specified voltages are 110V, 120V, 200V, 220V, 230V, 240V, 380V, 400V, and 480V. Because our standard and custom design capabilities can meet a range of power system needs, Georatoris your supplier forfrequencyto voltage converters.

Details:

  • Static Frequency Converter units are power converters, converting incoming AC power into DC power (rectifier stage) and then converting the DC power into the required AC frequency and voltage. Solid state frequency converters are ideal where noise, size, precision or adjustability are paramount. Solid state frequency converters are inherently quiet, which makes them ideal for office and laboratory environments. Typical noise levels are less than or equal to 65 decibels (dB). The common phase conversions are single phase to three phase and three phase to single phase.

Typical Characteristics of Sakthi Solid State Frequency Converters
  • Single and three phase units available, with optional phase conversion (e.g. 3 phase to single phase, single phase to 3 phase ). 
  • Suitable for use with Resistive, Capacitive, Inductive and Non-linear loads.
  • Galvanic Isolation input to output. No Harmonic Distortion (EMI, EMC).
  • Pure and Stable Sine wave Output.
  • Sustained 300% Overload Capability.
  • IGBT or MOSFET based, generating High Efficiency, Low Noise and Max. Reliability.
  • Utilize PWM technology enhancing Compact Size, Light Weight.
  • Equipped with Protection Circuits and Alarms.

What are some of the limitations of solid state frequency converters?
  • Solid state frequency converters are not very good at starting motor loads because of the typical motor starting surge current required to start motors.  Motor loads require a significant (6 to 10 times full load amps) kick simply to start to run.  This motor starting surge, also called “locked rotor” current, is momentary, only last a few milliseconds at peak, and decaying to normal running current in roughly a second.  Unfortunately, a solid state converter doesn’t “know” that this large surge will only last milliseconds, so it shuts down to self-protect.  To run motor loads, the converter’s overload ability must be matched to the motor starting requirement, causing a significant oversizing of the converter.
  • Solid state converters are also sensitive to temperature and humid environments.  In essence, they require air conditioning, and are not tolerant of severe environments, such as salt fog.  They have a typical lifetime of 10 years of continuous service.
