Method and device for controlling the frequency of a starting converter as a function of the frequency of an operating converter

摘要

The subject-matter of the invention is a method and a device for controlling the frequency of a starting converter (2) during starting at a frequency which is predetermined by an operating converter (1), with phase-correct synchronisation and, during slowing down from a frequency which is predetermined by the operating converter (1), at a lower frequency. The frequency which is supplied to the starting converter (2) is increased during starting and/or is reduced during slowing down in inverse proportion to the frequency of the operating converter (1).
