  • Publication number: 20240032261
    Abstract: A low inductance power module with low power loop inductance and high-power density is provided. The power module may include a vertical power loop structure, a cooling layer, and a thermal dissipation structure. The vertical power loop structure may utilize a substrate bottom conduction layer for electrical conduction. The thermal dissipation structure may be disposed between the substrate bottom conduction layer and the cooling layer. The vertical power loop structure may include integrated decoupling capacitors. Alternatively, the structure may include no integrated decoupling capacitors. The vertical power loop structure may include one or more half-bridge structures connected in parallel, each with its own integrated decoupling capacitors. The vertical power loop structure reduces power loop inductance in the power module, and the thermal dissipation structure provides electrical insulation, mechanical support, and thermal conduction.

  • Publication number: 20210098982
    Abstract: A reliable short-circuit protection scheme for all switching power devices is presented. This protection scheme includes an ultra-fast short-circuit detection component to quickly detect that a short-circuit may be occurring, a voltage clamping component to prevent short-term damage to the device, and a detection component that performs a system safe shutdown of the device in the event that a conventional slow over-current detection procedure verifies the short-circuit. This protection scheme can be applied to all switching devices and is especially suitable for wide bandgap (WBG) power devices which features high di/dt and high dv/dt switching capability. This protection scheme features reliable detection and protection, easy implementation, and low cost.
