AI Technical Summary
Existing power electronic devices face challenges in reducing parasitic inductance within the power module, leading to voltage stress and power loss, despite the use of laminated bus bars and external circuit designs that control loop inductance outside the module.
A component structure featuring laminated bus bars inside the power module and stacked bus bars at the fan-out terminals, where the first and second bus bars are laminated in parallel, and the rear portion of the second bus bar and the third bus bar are settled in parallel with the external circuit, reducing parasitic inductance between fan-out terminals.
This design effectively reduces parasitic inductance inside the power module, minimizing voltage stress and power loss, thereby enhancing the reliability and safety of power electronic devices.
