Applications of a controlled electric drive with reactive power compensation

Аннотация

The article gives the possibility of using a regulated electric drive with reactive power compensation. At the same time, the advantage of using frequency converters is analyzed, which allows saving energy, which is actual for today.Methods for improving the shape of the input current or for compensating the reactive power are given. These theoretical concepts are justified by a description of the graph of the dependence of the efficiency of an induction motor 4AI160S4 on the load
