Abstract: A semiconductor device includes a semiconductor body having first and second opposing surfaces in a vertical direction, and transistor cells at least partly integrated in the semiconductor body. Each transistor cell includes first and second source regions, first and second body regions, a drift region separated from the respective source region by the corresponding body region, a first gate electrode, and a control electrode. The drift region is arranged between the first and the second body region in a horizontal direction that is perpendicular to the vertical direction and extends from the first surface into the semiconductor body in the vertical direction. The first gate electrode is configured to provide a control signal for switching the transistor cell. The control electrode is configured to provide a control signal for controlling a JFET formed by the first body region, the drift region, and the second body region.

Abstract: A system for compensating one or more DC components in an electrical system includes one or more sensors for sensing the one or more DC components. The system also includes one or more DC component controllers for generating one or more reference signals from one or more signals received from the one or more sensors. In addition to this, the system also has one or more controllers for generating one or more firing pulses from the one or more reference signals received from the one or more DC component controllers and one or more valve configurations for charging one or more controllable branches to counterbalance the one or more DC components of the electrical system.

Abstract: A converter outputs reactive power and has three phase branches connected to a phase of an alternating voltage source. Each of the phase branches has a phase module with a series circuit containing two-pole sub modules. A voltage which is dropped across each phase module corresponds to the sum of the voltages which are dropped across the sub modules. The first and the third phase branch are electrically connected to one another by a magnetically coupled throttle pair. A control device controls phase module currents. The control device contains current controllers which are associated with the phase modules, a decoupling unit for decoupling control differences by a computational during control of the phase module currents, a coupling unit for correcting the decoupled computational actuating variables in accordance with the magnetic coupling of the first throttle pair to obtain corrected actuating voltages, and a control unit for driving the sub modules.
