Abstract: A bi-directional switch for an inductive machine is described. The bi-directional switch may include a first power semiconductor transistor with a first source, a first drain, and a first gate. The bi-directional switch may further include a second power semiconductor transistor with a second source, a second drain, and a second gate. The bi-directional switch may include the second source connected to the first source.

Abstract: A system and method for maintaining a temperature of a power system using a cooling system that includes an impeller and a phase change material. During normal operation of the cooling system, heat that is generated by the operation of an electronic device(s) of the power system can be transferred primarily by conduction through an upper base plate and fins of a heat sink, and dissipated via forced convection that is generated by the impeller. Additionally, the phase change material is positioned outside of a main heat flux path of the heat sink such that, during normal operation of the cooling system, the phase change material does not provide a heat flux obstruction. In the event of an impeller failure, the phase change material provides at least a temporary cooling source for an extended period of time via the relatively large latent heat capacity of the phase change material.

Abstract: In one aspect, a solid-state circuit breaker (SSCB) is provided. The SSCB is configured to generate a first output representative of a current through a current path of the SSCB. An analog fault detection circuit is coupled with first output and is configured to assert a second output in response to the current exceeding a trip current level. At least one analog-to-digital converter (ADC) is configured to generate samples of the first output, where the at least one ADC has a di/dt detection bandwidth that is less than a di/dt detection bandwidth of the analog fault detection circuit. The SSCB is further configured to disable the current path through the SSCB in response to determining, asynchronously, that either the second output is being asserted by the analog fault detection circuit or the samples indicate that the current through the current path exceeds the trip current level.

Abstract: A power semiconductor circuit is provided for clamping the voltage across the circuit when a power semiconductor switch is opened (i.e., turned off). The circuit may include a first surge arrester and a first semiconductor switch coupled in parallel with the power semiconductor switch. The first semiconductor switch is coupled in series with the first surge arrester. A second surge arrester may be coupled to the gate of the first semiconductor switch to control current flow through the first semiconductor switch and the first surge arrester.
