TY - JOUR A1 - Raab, Sebastian A1 - Weickert, Sebastian A1 - Kasten, Henning T1 - Methodology for Designing Broadband DC Link Filters for Voltage Source Converters JF - electronics N2 - This paper presents a new methodology for the design process of DC ripple filters for voltage source converters. It focuses on fast-switching, wide-bandgap-material-based converters. Therefore, a wide frequency range of up to 100 MHz is taken into consideration during the whole process. Different tools like analytic calculations, time-domain modelling, and the finite element method are used for different tasks in order to generate a realistic model in terms of filter effect and reliability. The models are validated by small-signal measurements using a vector network analyser as well as realistic high-power tests. The contribution of this paper is to provide a tool for DC link filter design to estimate the filter efficiency and the current stress on the filter elements with a special focus on WBG hardware.

It consists of multiple H-bridges connected in parallel and switched sequentially. As the effective switching frequency is a multiple of the switching frequency of each single switch, the bandwidth is scaled by the number of H-bridges in parallel. The prototype presented supports a maximum number of eight H-bridges in parallel.

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.
