Abstract
The paper deals with the design of DC-side filters for three-phase voltage source converters of drives connected to an industrial or automotive DC-grid. It points out the problem of designing a filter if the DC-grid impedance and structure are unknown. Therefore, it presents a new non-linear hybrid filter whose filter effect is less dependent on the impedance of the downstream DC-grid and with better immunity against external interferences. The analytical and simulation based design process is explained with help of a concrete example. Results are validated by measurements on an experimental set-up.
