Electric power converter e.g. three-phase converter, controlling device, has control circuit with determining module to determine control component based on modulation signals and current signal flowing in outputs of arms of converter

摘要

The device has a control circuit with a determining module (9) to determine a general control component for processing an over-modulation. The module (9) has a detecting module (22) to detect a current signal flowing in outputs of arms of a converter for being used in selection of a modulation signal receiving the over-modulation. The module (9) determines the component according to a set of modulation signals and the signal. Independent claims are also included for the following: (A) an electric power converter (B) a method of controlling an electric power converter.
