Abstract

A component arrangement. One embodiment includes a power semiconductor component having a drift zone arranged between a first and a second component zone. A drift control zone is arranged adjacent to the drift zone and is dielectrically insulated from the drift zone by a dielectric layer. A capacitive storage arrangement is coupled to the drift control zone. A charging circuit is coupled between the first component zone and the capacitive storage arrangement.
