Embodiment 1
[0068] Such as Figure 1-9 As shown, the invention of this example provides a controllable voltage source type sub-module protection method. The method of the present invention obtains the thermal stress state of the key position of the sub-module and components by measuring the temperature of the key position of the sub-module and inverting the internal junction temperature of the power electronic device through the thermal circuit model at the same time; The temperature of key positions and components in the sub-module is compared to realize the protection of the overheating fault of the controllable voltage source type sub-module.
[0069] The invention provides a typical half-bridge sub-module based on an IGBT device. The electrical diagram of the half-bridge sub-module 1 is attached figure 1 As shown, it includes a secondary board 2, an IGBT module 3, a discharge resistor 4 and a DC capacitor 5. Wherein, the IGBT module 3 and the secondary board 2 are key positions whe...
