Description

Power electronic converters emit strong electromagnetic interferences. Suitable grid filters must be added for connection to the power grid in order to meet EMC requirements. The inductive components in such grid filters, particularly for inverters working with power > 50 kW, represent a significant cost percentage of the complete system. The aim of the project is therefore to develop an innovative inverter system that can reduce electromagnetic interferences through a combination of intelligent filters and AI-supported control software. Within the framework of the project, the high-frequency emission spectrum in the power unit of the inverter system is to be influenced, dependent on the operating parameters, so that, for instance, saturation effects in the filters are limited to maintain filter effectiveness.
