Abstract

The paper presents a full SiC power module for Vienna rectifiers with ultra-low commutation loop inductance based on double-side sintering technique. The neutral point of DC bus was split into two parts so that two commutation loops can be decoupled. And it makes the layout design more flexible. Then a symmetric structure was proposed. The structure reduces the parasitic inductance and improves the thermal performance. Then a RC network was applied to suppress the voltage overshoot across MOSFET and the oscillation of DC bus voltage. And the method of selecting proper decoupling capacitance and damping resistance was derived by parameter sweep. The simulation results show that the optimized structure is superior to the conventional one. With the optimized structure, the inductance of commutation loop decreases by 41.6% and the maximum junction temperature decreases by 12.6°C.
