This paper presents a design methodology for a high power density converter, which emphasizes weight minimization. The design methodology considers various inverter topologies and semiconductor devices with application of cold plate cooling and LCL filter. Design for a high-power inverter is evaluated with demonstration of a 50 kVA 2-level 3-phase SiC inverter operating at 60 kHz switching frequency...
To drive SiC power module with high-speed switching, the stray inductance becomes a key factor in converter design. In this work, the stray inductances of module and peripheral circuits are investigated by simulation and measurement. With the loop stray inductance of 29.2 nH, the module is tested up to 800 V and 50 A with insignificant EMI issues of ringing and overshoot. And the dv/dt ratios at turn-off...
