    摘要: A half bridge is described with at least one transistor having a channel that is capable in a first mode of operation of blocking a substantial voltage in at least one direction, in a second mode of operation of conducting substantial current in one direction through the channel and in a third mode of operation of conducting substantial current in an opposite direction through the channel. The half bridge can have two circuits with such a transistor.

    摘要: A multilevel inverter includes a first half bridge in series with a second half bridge, each comprising a switch having a channel. The switch is configured to block a substantial voltage in a first direction during a first mode of operation, to conduct substantial current through the channel in the first direction during a second mode of operation, and to conduct substantial current through the channel in a second direction during a third mode of operation. During the third mode of operation, a gate of the switch is biased relative to a source of the switch at a voltage that is less than a threshold voltage of the switch. The inverter may also include a third half bridge. The inverter can be configured such that in operation, switches of the third half bridge are switched at a substantially lower frequency than the switches of the first and second half bridges.

    摘要: 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.

    摘要: 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.
