Introduction Thi paper preent an overmodulation cheme of NPC type three-level inverter and an indirect vector control of induction motor for traction drive. Recently railway vehicle have operated at higher peed within the limited plant for higher efficiency. The conventional railway vehicle ha ued the vector control to the modulation factor of 90.7% with pace vector PWM (SVPWM) and ued the lip-frequency control to ix-tep mode. The lip-frequency Manucript received January 0, 2009; revied April 8, 2009 Correponding Author: choi@chungbuk.ac.kr Tel: , Fax: , Chungbuk Nat l Univ. School of Electrical and Computer Engineering, Chungbuk National Univerity, Cheongju, Korea R&D Center, LS Indutrial Sytem Co. Ltd., Cheonan, Korea control i uitable for traction drive, becaue the drive pattern of electric railway ytem do not requet a rapid change. However, that control can not realize a quick torque repone. In high-peed train, the lip between train wheel and rail i likely to occur, and the fat torque control i crucial to overcome thi lip problem. The vector control provide an intantaneou torque repone becaue it i poible to control the flux and torque of the induction motor independently. An overmodulation cheme of SVPWM with modulation factor 90.7% to unity i eential if the drive can meet the operation at extended peed including the field weakening region in vector control with higher torque and power characteritic. The overmodulation trategy of a two-level inverter and it implementation ha been tudied [1,2]. The NPC type three-level inverter ha three output voltage

Becaue of thi nature, it ha been applied to the medium and high voltage drive. In addition to the capability to handle the high voltage, the NPC type three-level inverter ha favorable feature; lower line to line and common-mode voltage tep, more frequent voltage tep in one carrier cycle, and lower ripple component in the output current at the ame carrier frequency. Thee feature lead to ignificant advantage for motor drive over the conventional two-level inverter in the form of lower tree to the motor winding and bearing, le influence of noie to the adjacent equipment, etc []. Recently, mot Japanee electrical train companie have developed a three-level PWM inverter drive ytem for traction drive. It i well known that the three-level configuration ha greatly reduced the ize of the main tranformer and traction-motor, the current harmonic in the ignaling band, the acoutic noie, and the volume and weight of the equipment [4]-[7]. Alo, the power rating of the ytem can be increaed. However, SVPWM of a three-level inverter i coniderably more complex than that of a two-level inverter due to the large number of inverter witching tate. Beide, there i the problem of neutral point voltage balancing [8]. There have been ome tudie on the over-modulation trategy of three-level inverter, but few of them are focued on the application of traction drive. Mot of them are limited to the modulation itelf and lack of experimental implementation [9]-[11]. Thi paper decribe a SVPWM over-modulation cheme of the NPC type three-level inverter that extend the modulation index from MI=0.907 to unity [12]. SVPWM trategy i organized by two operation mode of under-modulation and over-modulation. The witching tate under the under-modulation mode are determined by dividing them with two linear region and one hybrid region the ame a the conventional three-level inverter. On the other hand, under the over-modulation mode, they are generated by doing thi with two over-modulation region which i the ame a the conventional over-modulation trategy of the two level inverter. Following the decription of the over-modulation cheme of the three-level inverter, the ytem decription of a vector controlled induction motor for traction drive ha been dicued. Finally, the validity of the propoed modulation algorithm ha been verified through the imulation and experimental reult. 2. NPC type Three-level Inverter The NPC type three-level inverter ha three output voltage level. With thi circuit configuration, the voltage tre on it power witching device i half that of the conventional two-level inverter. Becaue of thi nature, it ha been applied to the medium and high voltage drive. In addition to the capability to handle the high voltage, the NPC type three-level inverter ha favorable feature; lower line to line and common-mode voltage tep, more frequent voltage tep in one carrier cycle, and lower ripple component in the output current at the ame carrier frequency. Thee feature lead to ignificant advantage for motor drive over the conventional two-level inverter in the form of lower tree to the motor winding and bearing, le influence of noie to the adjacent equipment, etc. Fig. 1 how the chematic diagram of a three-level IGBT inverter with induction motor load.
