Frequency converters, also known as frequency chargers, are designed to convert 50Hz and 60Hz power to 400Hz. Different mechanisms are used to achieve this conversion, including static frequency converters or rotary frequency converters, which use a motor generator to convert power across different frequencies. Basically, frequency converters are machines that can convert power across different frequencies.
The conversion process can be via double conversion which utilizes static frequency converters, or with a motor generator called rotary frequency converter. In the double conversion method, rectifiers are used in converting AC to DC with the inverter converting DC to AC. On the other hand, the motor generator performs the conversion by changing rotational speed of the generator.
There are so many interesting things to note about frequency converters, and this article will take you through some of the key things about frequency converters, including their role in industrial applications.
Before we continue with their roles in industrial applications, here are some types of frequency converters you should know:
Single Phase Converter: Single-phase static frequency converters feature versatile communications platforms for network, local, or remote control and monitoring. They also feature communication packages like USB and RS-232 Serial port.
Static Frequency Converter: They make use of 6 and 12 pulse, including IGBT topology to boost the efficiency of solid-state frequency conversion. This is an advancement that sets them apart when compared to other types of frequency converters. They are also designed to provide support for equipment, even in extreme electrical conditions.
Dynamic Frequency Regulator: They are designed to offer a greater level of reliability to control equipment and power systems. This is because they are designed based on hybrid rotary technology. Dynamic frequency regulators are available from 25 to 500 kVA.
Rotary Frequency Converter: They offer reliable power to equipment, in addition to converting voltage to frequency. The rotary frequency converter also serves as a rotating filter to protect against blowouts.
Different industries have their frequency requirements, and this is mostly according to how they supply power to equipment. Weapon and aviation systems require 400Hz, and with that, equipment that is used on the ground and operates at 400Hz will require ground power support.
Rail systems utilize 100Hz, 91.55Hz, or 25Hz to operate their signaling systems. Boat docks and shipyards also need shore power conversion mechanisms. In 50Hz countries, there are usually power system that operate at the same frequency, and will require a frequency converter to meet the electrical needs of the ships that are build, docked, or repaired in such countries.
In cases where equipment are manufactured in one country and utilized in another country, the need to convert voltage is usually higher. This also applies to frequency as well. In general, 50Hz and 60Hz are the most common frequencies and you’ll find this on most commercial machines. However, there are also applications that will require conversion to higher frequencies. There are so many applications of frequency converters, and this cuts across different industries.
Frequency converters are a popular device, as mentioned above, and they are used in many industries, including aviation and shipping industries, where there’s a need to bridge between 400, 60, and 50HZ. Frequency converters provide an effective means to alternate the current of a frequency to another frequency. This process offers multiple benefits, which include the following:
With frequency converters, you can run a pump or motor at an efficient speed and still match the motor to any power requirement. This will help in ensuring that the motor doesn’t overwork, thereby improving the efficiency and overall cost of running the motor or the pump.
Because machines run at a more efficient and slower speed, frequency converters will ensure that they run better and for a longer period to reduce the need for frequent maintenance, which could be expensive. This doesn’t mean that proper and regular maintenance isn’t good, but you won’t need to spend so much on unnecessary maintenance.
Basically, frequency converters provide an efficient way to run motors and pumps, thereby increasing the lifetime of machines. Without a frequency converter, your machines won’t last as long as they would if you have a frequency converter. This is because running at a more efficient speed will put lesser pressure on your machine, and this will reduce the number of repairs and replacements you’ll have to make.
Using frequency converters also helps businesses to improve their processes because it gives them more control over the speed of machines. Successful performance of industries depends on processes, and with frequency converters, processes can be improved significantly.
Unlike the general belief that frequency converters are expensive, they are actually a lot cheaper than they used to be. With this reduced price of frequency converters, they are a small investment that will allow you to reap so much more in the long run. Basically, frequency converters are a lot cheaper than flow control valves and a wide range of traditional starters.
Pumps and motors overseas usually utilize different frequencies. Therefore, including a frequency converter will reduce the chance of running into a problem and ensure that your equipment doesn’t develop any faults for as long as possible. As mentioned above, this will further help to increase the longevity of the equipment and give you a huge return on investment.
The importance of frequency converters cannot be overemphasized, and this is the main reason why they are currently utilized in many industries today. Despite the role they play in these industries, it’s important to always research well and review their various specifications before you choose a frequency converter to invest in. Rest assured that this type of investment will make your business see longer-lasting equipment and smaller costs of maintaining this equipment.
