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 customer requirements. 1. Introduction In recent years, initiatives to reduce CO2 emissions in order to protect the environment have been implemented in countries throughout the world. The shift to clean energy, such as to wind power and solar power, which does not rely on conventional fossil fuels, is becoming increasingly prominent. The use of power electronics devices to conserve energy can be found in a wide variety of applications, from consumer electronics to electric railways, FA systems and the like. Moreover, power electronics are used not only in power-consuming applications, but their use has also spread to the fields of power generation, transmission and supply such as in uninterruptible power supplies (UPS), wind power generators and solar power generators. In particular, multi-...
