infineon IGBT串行连接
Series connection of IGBTs

Effective factors for voltage sharing:
static dynamic
device characteristics ICES, Tj Tj, Vgeth, tdon, tdoff, Qrr
driver - Lwire , ton, toff
Recommendations:
use devices of one production lot (smallest parameter deviations guaranteed)
symmetrical design of gate driver (minimize deviations of delays)
symmetrical cooling conditions (identical heat-sink temperature and flow rate
