중ㆍ대용량 인버터용 IGBT 병렬 운전 연구 = The Study on Parallel operation IGBT for the Medium & the Large capacity Inverter

다국어 초록 (Multilingual Abstract)

IGBTs are widely used for the industrial inverters in the mid power range at low voltage (440V -660V) application. Advantageous features of the device are simple gate drive and high speed switching capability. Due to these advantages the application of IGBTs is enlarging into the high power application. However, to increase the power handling capacity at lower input voltage level, the current rating m each bridge arm must be enlarged. Therefore the parallel operation of IGBT devices is essentially needed.<br/>
This paper describes the feasible parallel structures of the power circuit for the IT\1d & the high power inverters and introduces the important design condition for the parallel operation of IGBT devices.<br/>
To verify feasibility of the IGBT parallel operation, the feature of several IGBT devices (EUPEC, SEMIKRON's IGBT) are investigated and the power stacks are implemented and tested with these devices. The experimental results show the good characteristics for the parallel operation of IGBTs.
