20130049843 | REVERSE CONDUCTION MODE SELF TURN-OFF GATE DRIVER - There is provided a power electronic module that includes a power switch module and a drive circuit operatively coupled to the power switch module. The drive circuit is configured to enable and disable a forward conduction mode operation of the switch module. The drive circuit disables forward conduction mode operation of the power switch module when the power switch module is operating in reverse conduction mode. | 02-28-2013 |
20130154711 | METHOD, POWER UNIT, AND POWER SYSTEM HAVING GATE VOLTAGE LIMITING CIRCUIT - A power unit (e.g., inverter module) includes a housing and a switch attached to the housing. The switch may be configured to be electrically coupled to a remotely-mounted drive circuit through two or more wire leads. The power unit also includes a clamping circuit electrically coupled to terminals of the switch and in parallel with the switch. The clamping circuit may be disposed inside the housing or on an outer surface of the housing, and is configured to limit a voltage across the switch. | 06-20-2013 |
20150035585 | REVERSE CONDUCTION MODE SELF TURN-OFF GATE DRIVER - An apparatus includes a switch module, a sense circuit coupled to the switch module and configured to indicate an operating conduction mode of the switch module, and a drive circuit operatively coupled to the switch module to enable and disable forward conducting mode of the switch module. Once the switch module is in forward conducting mode, the drive circuit is configured to maintain enablement of the forward conducting mode even if the sense circuit indicates reverse conduction mode. | 02-05-2015 |

20120161852 | POWER SWITCH CURRENT ESTIMATOR AT GATE DRIVER - A power switch current estimator for a solid state power switch. The power switch includes a control terminal, an input current power terminal, and an output current power terminal. The power switch is further configured with at least one sense terminal. One or more parasitic elements define an electrical pathway between a power terminal and a corresponding sense terminal. A driver unit that selectively turns the power switch on and off is connected to the control terminal and a sense terminal. A current estimator generates an estimated level of current circulating through the solid state power switch in real time in response to one or more switching events of the power switch. The estimated level of current is based on values of at least one of the parasitic elements such that the estimated level of load current substantially corresponds to an actual level of load current circulating through the solid state power switch. | 06-28-2012 |
