Abstract: The loss angle tangent of the component of the DC-link capacitor affects the heating performance of the DC-link capacitor.This paper introduced the DC-link capacitor losses, the structure of the DC-link capacitor element, and the equivalent circuit. In addition, it studied the interfering factors which affect the loss angle tangent of DC-link capacitor components. This research designed metalized films with different specifications and elements with different diameters. Furthermore, it measured and analyzed the effect on the loss angle tangent. The result of this study could provide a reference for designing a DC-link capacitor and the model selection.
Key words: DC-link capacitor; component; tangent of the loss angle
