| Summary: | On the package requirements of SiC devices of high operate temperature, high power density and low stray inductance,a double side cooling SiC power module was designed. The simulation results displayed that the power module has good current balance and low stray inductance. To fully explore SiC module capability, a full Ag sintering process and process fl ow was developed.The samples were manufactured. The dynamic and static test displayed that samples haved good static and dynamic characteristic, and under the condition that the <italic>R</italic><sub>DS-on</sub> was 3.95 mΩ and drain source current <italic>I</italic><sub>d</sub> was 350 A, the total stray inductance <italic>L</italic><sub>s</sub> was 11.2 nH. The test shows that the full Ag sintereing double-sided heat dissipation SiC module has excellent dynamic and static performance and has great application prospect. |
