Abstract

All the companies of electrically-driven equipments are looking for the solutions with high reliability, low maintenance cost, and maximum efficiency with smaller installation space considering environmental issues. In this study, the development of a 5-level IGBT (Insulated Gate Bipolar Transistor) inverter is introduced which is applicable in the field of Oil and Gas Industry as a high speed, large capacity with high efficiency motor drive equipment. By decreasing the floating inductance from the unit, we materialize to develop the snubberless main circuit block. Thus, it is possible to downsize the equipment by reducing the parts. As one bank of this inverter capacity is 8MVA, it is possible to obtain 16MVA by connecting two banks in parallel. This paper also reports the results of motor combined test which illustrate the principle and mechanism of the 5-level inverter system.
