摘要： A system includes an electronic device including a circuit having a semiconductor switch, and a controller configured to control a gate driver connected to the semiconductor switch via a protection circuit. The controller is configured to set a protection parameter including a voltage threshold representing a selected value of a voltage across the semiconductor switch, the protection parameter configured to cause the semiconductor switch to be deactivated in response to an overcurrent condition, the protection parameter selected based on a mathematical model of the semiconductor switch, the mathematical model representing a physical property of at least one of the electronic device and the semiconductor switch.

摘要： A slew rate controllable system for powering an electric machine. The system may include a plurality of power transistors operable for converting a direct current (DC) input into an alternating current (AC) output suitable for electrically powering the electric machine. The system may further include a gate drive system operable for controlling a slew rate associated with transitioning the power transistors between the opened and closed states.

摘要： Aspects of the disclosure include a 1.5 sided cooled power module for enhanced cooling and gate connections. An exemplary cooled power module can include an upside direct bond copper (DBC) having a first top copper layer, a first bottom copper layer, and a first dielectric layer between the first top copper layer and the first bottom copper layer. A downside DBC includes a second top copper layer, a second bottom copper layer, and a second dielectric layer between the second top copper layer and the second bottom copper layer. One or more dies are positioned between the upside DBC and the downside DBC. The upside DBC is sized such that a portion of an uppermost surface of the one or more dies remains exposed. Bond wires are placed on the exposed portion of the one or more dies and terminated on the first top copper layer of the upside DBC.

摘要： Aspects of the disclosure include a symmetric direct current (DC) link capacitor having a low parasitic equivalent series L-inductance (ESL). An exemplary capacitor can include one or more positive-dielectric-negative (PDN) stacks having a positive layer, a negative layer, and a dielectric layer between the positive layer and the negative layer. A first contact layer is electrically coupled to the positive layer on a sidewall of the one or more PDN stacks and a second contact layer is electrically coupled to the negative layer on the sidewall of the one or more PDN stacks. A positive terminal is electrically coupled to the first contact layer and a negative terminal is electrically coupled to the second contact layer.

摘要： A system includes an electronic device including a circuit having a semiconductor switch, and a switching control system operably connected to the semiconductor switch. The switching control system is configured to control a switching speed of the semiconductor switch based on a received voltage by altering at least one of a gate resistance and a gate capacitance of the semiconductor switch.
