The failure mechanism of the single-phase power module for three-phase converter applications with high output power is investigated. It illustrates that the higher current density on the near-terminal side of the power device, along with the abreast bonding that induces thermal coupling at the second footprints of bond wires, together result in the failure of the power device in the module. Then,...
In hard cooperative spectrum sensing (HCSS) for cognitive radio (CR), where local secondary users (sensors) sense whether primary users exist or not and then send decisions to the center where the final decision is made, correlation between sensors has been conventionally believed and experimentally shown to have detrimental effects on performance of HCSS. In this paper, we restudy effects of correlation...
