摘要：
The high-speed switching of switch modules in the high-power electric drive system of armored vehicle power system will generate a series of high-voltage transient pulses and broadband harmonic interference, thus posing a serious threat to the highly electrified vehicle system. A system level constructing method for a conducted interference prediction model is proposed to address the lack of digital detection and analysis of conducted interference generated by high-power electric drive systems. Firstly, the models of electrical components, such as high-voltage battery pack, inverter, and load motor, of the electric drive system are constructed independently; secondly, based on the multi-conductor transmission line method, each model is cascaded through transmission lines that characterize the parasitic effects of the system, thereby forming a complete distributed system-level conducted interference prediction model; and finally, the accuracy of the proposed prediction model is test and verified through bench test. The verified results indicate that the proposed prediction model has a simulation accuracy of better than 8 dB in the frequency range of 10 kHz to 100 MHz, which can provide effective support for the forward design of electromagnetic compatibility of electric drive armored vehicle, and is innovative and practical. © 2024 China Ordnance Industry Corporation.
