Intelligent integrated power device with high power density and research on its parallel application
To overcome the limitations on the packaging and application structure of traditional power semiconductor devices and upgrade converters
this paper proposed a novel intelligent integrated power device with high power density. Its feasibility was investigated by focusing on common parallel application scenarios in the high-power converter field. The study primarily examined the four key influencing factors: device parameters
main circuit
heat dissipation structure
and drive control. It analyzed and validated the excellent device matching
inductance balance
heat dissipation uniformity
control signal synchronization
and anti-interference capability. Subsequently
the article demonstrated the favorable parallel current sharing effect through the double pulse test and power assessment test. The experimental results show the achievement of the theoretical design and physical verification objectives of this technology platform
establishing a strong foundation for future engineering applications.
