Patent number: 10622909Abstract: An inverter for an electric vehicle drive has a bridge configuration using power transistors packaged in actively cooled power modules. Control electrodes in the power modules carrying gate signals to drive the transistors contain inductive coils to increase a common source inductance in order to reduce power losses. Each inverter power module comprises a pair of transistor dies with output electrodes defining a power loop. The control electrodes with inductive coils carrying respective gate signals are arranged to be magnetically coupled with the power loop. For active cooling, a heat conductive plate underlies the dies. A magnetic interrupter is disposed at the heat conductive plate. A localized eddy current preventer is interposed at the heat conductive plate in alignment with the inductive coils to avoid eddy currents that could otherwise reduce the coupling of the inductive coils with the power loop.Type: GrantFiled: January 12, 2017Date of Patent: April 14, 2020Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Zhuxian Xu, Guangyin Lei, Chingchi Chen
