Comments Off on A Novel DBC Layout for Current Imbalance Mitigation in SiC MOSFET Multichip Power Modules
Posted in: IEEE 2017, Power Electronics
A Novel DBC Layout for Current Imbalance Mitigation in SiC MOSFET Multichip Power Modules Abstract: This letter proposes a novel direct bonded copper (DBC) layout for mitigating the current imbalance among the paralleled SiC MOSFET dies in multichip power modules. Compared to the traditional layout, the proposed DBC layout significantly reduces the circuit mismatch and […]
