摘要：
The aim of this paper is to minimize an all-pole sine filter by increasing the switching frequency so that it can be integrated into a SiC drive inverter. For this purpose, theoretical considerations of the influence of the switching frequencies on the size and losses of the inductor, the capacitor, the semiconductor, and the heat sink size for the semiconductors were carried out. A parameter study of a filter concept as a function of the switching frequency has been discussed. Detailed analysis of three inductors is made, which consist of various simulation models. Two prototypes of all-pole sine filters are built for a switching frequency of 128 kHz. These two prototypes were operated in a drive system consisting of a SiC drive inverter and motor to measure and evaluate the filter effect and thermals of the filters. The filter behavior in the event of overload is also discussed.
