  • Publication number: 20230074505
    Abstract: A converter includes first and second transistors coupled between first and second nodes, and first and second thyristors coupled between the first and second nodes. The converter is controlled for operation to: in first periods, turn the first transistor and second thyristor on and turn the second transistor and the first thyristor off, and in second periods, turn the first transistor and the second thyristor off and turn the second transistor and the first thyristor on. Further control of converter operation includes, for a third period following each first period, turning the first and second transistors off, turning the second thyristor off, and injecting a current into the gate of the first thyristor. Additional control of converter operation includes, for a fourth period following each second period, turning the first and second transistors off, turning the first thyristor off, and injecting a current into the gate of the second thyristor.

  • Publication number: 20220393022
    Abstract: A trench in a semiconductor substrate is lined with a first insulation layer. A hard mask layer deposited on the first insulation layer is used to control performance of an etch that selectively removes a first portion of the first insulating layer from an upper trench portion while leaving a second portion of first insulating layer in a lower trench portion. After removing the hard mask layer, an upper portion of the trench is lined with a second insulation layer. An opening in the trench that includes a lower open portion delimited by the second portion of first insulating layer in the lower trench portion and an upper open portion delimited by the second insulation layer at the upper trench portion, is then filled by a single deposition of polysilicon material forming a unitary gate/field plate conductor of a field effect rectifier diode.
