Abstract
A circuit that includes a filter and a DC bus is provided that reduces the potential for failure of a second capacitor of the filter in the event a first capacitor shorts. The filter is electrically connected across the DC bus and includes serially connected capacitors and a capacitor fuse electrically connected in series with the capacitors. The capacitor fuse is adapted to open in the event a first capacitor of the series shorts in order to prevent failure of a second capacitor of the series. In one embodiment of the invention, a static power converter includes a pair of serially connected capacitors having a DC bus fuse serially connected therewith. In another embodiment of the invention, a filter connected across a DC bus includes a plurality of capacitor legs that each include a capacitor fuse serially connected to a plurality of serially connected capacitors.
