IGBT Module Series for Advanced-NPC Circuits
Kosuke Komatsu † Takahito Harada † Yoshiyuki Kusunoki †
ABSTRACT A series of insulated gate bipolar
transistor (IGBT) modules has been developed to enable advanced neutralpoint-clamped (A-NPC) inverters.
Modules in this series integrate A-NPC circuits for three phases with thermistors in a single package.
Loss is minimized by the adoption of 6th-generation IGBT, free wheeling diode (FWD) and reverse blocking IGBT (RB-IGBT) devices.
Power dissipation is reduced by 51% compared to conventional two-level inverters and by 33% compared to conventional NPC three-level inverters.
Two types of pin configuration are available, and selectable according to cu...
