  • Publication number: 20130320939
    Abstract: Power switching circuits including an inductive load and a switching device are described. The switches devices can be either low-side or high-side switches. Some of the switches are transistors that are able to block voltages or prevent substantial current from flowing through the transistor when voltage is applied across the transistor.

  • Publication number: 20120218025
    Abstract: An electronic component comprising a half bridge adapted for operation with an electrical load having an operating frequency is described. The half bridge comprises a first switch and a second switch each having a switching frequency, the first switch and the second switch each including a first terminal, a second terminal, and a control terminal, wherein the first terminal of the first switch and the second terminal of the second switch are both electrically connected to a node. The electronic component further includes a filter having a 3 dB roll-off frequency, the 3 dB roll-off frequency being less than the switching frequency of the switches but greater than the operating frequency of the electrical load. The first terminal of the filter is electrically coupled to the node, and the 3 dB roll-off frequency of the filter is greater than 5 kHz.

  • Patent number: 7875907
    Abstract: Bidirectional switches are described. The bidirectional switches include first and a second III-N based high electron mobility transistor. In some embodiments, the source of the first transistor is in electrical contact with a source of the second transistor. In some embodiments, the drain of the first transistor is in electrical contact with a drain of the second transistor. In some embodiments, the two transistors share a drift region and the switch is free of a drain contact between the two transistors. Matrix converters can be formed from the bidirectional switches.
