Introduction to Frequency Converters
In various industries, equipment where rotational mechanisms on electric drives play a key role is widely used. During the operation of such devices in different modes, the nature of the current supply varies. To ensure stability in various operational scenarios, this equipment requires current frequency converters.
Principle of Operation of a Frequency Converter
A frequency converter is a device that receives input voltage with a certain frequency and converts its signal at the output according to the required characteristics for the serviced mechanism. In different types of converters, the voltage is adapted to the output parameters in two main ways:
- Rectification of the signal. In this case, the output current has reduced voltage indicators. Such converters operate with direct connection, making the control circuits simple and cheaper to manufacture.
- With increased frequency. In devices of the second type, the current comes out with an increased or equal output parameter frequency. They have a pronounced constant type link, which requires a dual automation system, resulting in a higher cost.
Applications of Frequency Converters
Frequency converters are widely used in all situations where it is necessary to stabilize the voltage in the network while operating electrical units. This is especially relevant for industrial production, where powerful machines can cause sharp and significant fluctuations in current frequency. Frequency inverters help avoid short circuits in the network and in the units themselves, significantly reduce noise levels, and save electricity.
When repairing in residential, office, and production premises, the use of frequency converters significantly improves the operation of electrical devices of small mechanization.
Advantages in Everyday Life
In everyday life, frequency converters are invaluable, especially for devices with medium or high power. This applies not only to household air conditioners and computer units but also to other automated electrical devices, including automatic gates and doors.
Who Needs Frequency Converters?
Depending on the application environment, frequency inverters are in demand among specialists who service electrical appliances with high current consumption. Builders and companies engaged in the construction and demolition of buildings will purchase these devices to optimize costs and prevent electrical wiring failures.
Production managers who require continuous operation of powerful pumping stations are also interested in acquiring inverters to optimize the operation of pumping devices. These devices become an integral part of the budget for enterprises in the utility sector.
Frequency current converters are a radical and positive solution for all industries where complex electrical mechanisms with increased electricity consumption are used.
