Direct frequency converters (cycloconverters) with close to sinusoidal output voltage
The article describes the structure and operation of voltage converterof a high-speed turbogenerator set (6000 rpm), providing the creation of an output voltage with a frequency of 50 Hz in the form of a curve close to a sinusoid
Testing of frequency converters in Ukraine
Improving the fleet of industrial enterprises due to chastotniks has become a recent trend in Ukraine. The increase in the cost of energy carriers and the redirection of factories to European markets require a review of the cost and quality of products
Single-phase and three-phase frequency converters
Any frequency converter, regardless of the supply voltage, is used to adjust and control electric motors. At the moment, there are three main categories of frequency converters, which differ in phase
Frequency converters and EMC filters
Frequency and compatibility from time to time a hotly discussed topic, as well as the topic of reports at conferences. It is worth giving a definition of electromagnetic compatibility:Electromagnetic compatibility of technical devicesmdash their simultaneous functioning in real operating conditions with
How to choose the right frequency converters with low harmonics?
I was inspired to write this article by a e from a frequency supplier: “The use of anti-harmonic technology has helped to achieve THDI (Though Harmonic Distortion) values u200bu200bbelow 30% without the use of additional filter elements.”
What are petrol and gas generators used for?
Gasoline Generator this is a source of electrical energy for garage farms, summer cottages, private houses, etc.
Gearmotor: varieties and selection criteria
A gearmotor is, in fact, a mechanism that simultaneously combines two functions in one: on the one hand this is an electric motor, on the other, directly, a gearbox. Such devices are used in almost all industrial
