STATIC SEMICONDUCTOR CONVERTERS WITH IMPROVED RELIABILITY AND ELECTROMAGNETIC COMPATIBILITY ON THE BASIS OF A TRANSFORMER WITH A ROTATING MAGNETIC FIELD
Anoverviewofmodernstaticconverters, aswellas different ways of frequency conversion, including pulse-width modulation.The analysis of their shortcomings, leading to a decrease in the reliability and electromagnetic compatibility of equipment autonomous EPS.Allocated a separate class of industrial users that require the power of low frequency without its regulation, including dewaxing system and a number of other industrial consumers. A new type of direct frequency converter based on a transformer with a rotating magnetic field, allowing to implement the algorithm switching without breaking the current curve, which improves the electromagnetic compatibility with the power supply and other electrical equipment, as well as increases the reliability of the semiconductor valves. The analysis of its advantages and disadvantages relative to other types of frequency converters.
