Aspects of the present disclosure involve a power module, which may include an inverter circuit employing semiconductor switch dies. In the presence of a failure of a die, which may include an arc from a short, a sensor produces a signal responsive to the failure. The signal initiates an indirect fuse, such as a pyrotechnic element, that opens conductors associated with the die. For example, the die or a related die may be wire bonded to terminals of the module. The indirect element may therefore open the bonds to the terminals to isolate the failed die and/or related dies.

Self clearing power module

Aspects of the present disclosure involve an inverter employing switches of different types in parallel. In one example, an apparatus includes a voltage-source converter that may have a plurality of switch positions collectively coupled to convert an input to an output. At least one switch position may include a first switch of a first switch type and a second switch of a second switch type different from the first switch type. Also, the first and second switches may be coupled in parallel. The converter may also include a switch control circuit to generate, for each of the at least one of the switch positions, a first control signal to operate the first switch of the switch position, and a second control signal to operate the second switch of the switch position.

Converter employing differing switch types in parallel

Power semiconductor devices according to embodiments of the present technology may be operated to protect components of the semiconductor device. Methods for operation of the devices may include measuring a temperature within a source region of the semiconductor device. The methods may include measuring at the semiconductor device an amount of current associated with a short circuit external to the semiconductor device. The methods may include predicting a temperature effect within two regions of the semiconductor device based on a range of distribution of the amount of current between the two regions of the semiconductor device. The methods may include determining a particular distribution of the amount of current between the two regions of the semiconductor device. The methods may also include shutting off the semiconductor device to cause the particular distribution of current between the two regions of the semiconductor device.

Deterministic shutdown of power module

A power inverter circuit includes a capacitor and a power module. The capacitor includes a positive plate and a negative plate that are spaced apart along opposing sides of the capacitor and extend toward each other along a common side of the capacitor. The power module includes a positive connector and a negative connector that are connected to the positive plate and the negative plate, respectively, and are spaced apart and extend parallel across from each other.

Distributed control pole clamp circuit for gate driver

A shelf that is adapted for engaging the cargo basket of a shopping cart, the cargo basket having a frame made of metal wire. The shelf providing a platform having a leading edge of a leading edge length and an aft edge of an aft edge length, the platform having spaced apart sides that extend from the aft edge to the leading edge. Each of the sides of the platform having opposing side hooks, each side hook extending away from a respective side and further extending down and terminating in a side hook tip that lies below aft edge of the platform, so that the shelf is adapted for attaching to the frame of the cargo basket by engaging the forward edge of cargo basket with the end hooks, and engaging the sides of the cargo basket.
