Provided herein is a power distribution system comprising a main power bus, sub-buses coupled to the main power bus, and a controller. The sub-buses provide power to electrical components of a vehicle. Each of the sub-buses includes an electrically programmable fuse in series with a relay. The controller is configured to detect a fault in a sub-bus of the sub-buses, determine a fault type associated with the fault, and in response to determining the fault type, generate a command to cause the relay to change a relay state.

A placement base (100) of a semiconductor device (90) comprises a body (10) on which the semiconductor device (90) is disposed, and a fixing unit (40) for fixing the semiconductor device (90) to the body (10). The body (10) has a supporting unit (12) and a bottom surface (11) placed in an inner periphery of the supporting unit (12) and placed lower than the supporting unit (12). A difference in height ΔH between the supporting unit (12) and the bottom surface (11) is larger than a sum (H1+H2) of a calculated or measured maximum upward warp H1 of the bottom surface (11) and a calculated or measured maximum downward warp H2 of a base of the semiconductor device (90).

An electrical contactor assembly includes an electrical contactor, a post in electrical communication with the electrical contactor, an insulator body, and a heat sink. The insulator body is in intimate mechanical contact with the post. The heat sink is in intimate mechanical contact with the insulator body and is in thermal communication with the electrical contactor through the post and the insulator body such that heat flowing between contactor and the heat sink flows through the post and the insulator body.
