  • Publication number: 20120170339
    Abstract: A rectifier circuit with a synchronously controlled semiconductor element comprising at least one field effect transistor with a control electrode and two switching electrodes. The control electrode operates the reverse state and the forward state between the switching electrodes. For this, the rectifier circuit comprises at least one driver which cooperates with a voltage sensor of the field effect transistor. During the diode operating state of the field effect transistor, the driver operates this to the forward state. The voltage sensor thereby forms at least one part of a non-linear voltage divider which comprises at least one monolithically integrated measuring capacitance.

  • Publication number: 20110121437
    Abstract: A semiconductor device includes a drift zone of a first conductivity type formed within a semiconductor body, wherein one side of opposing sides of the drift zone adjoins a first zone within the semiconductor body and the other side adjoins a second zone within the semiconductor body. First semiconductor subzones of a second conductivity type different from the first conductivity type are formed within each of the first and second zones opposing each other along a lateral direction extending parallel to a surface of the semiconductor body. A second semiconductor subzone is formed within each of the first and second zones and between the first semiconductor subzones along the lateral direction. An average concentration of dopants within the second semiconductor subzone along 10% to 90% of an extension of the second semiconductor subzone along a vertical direction perpendicular to the surface is smaller than the average concentration of dopants along a corresponding section of extension within the drift zone.
