Recently, a high-speed, large capacity compressor is applied in industrial fields. The methods of driving the compressor with the steam turbine and the gas turbine were traditional methods, and the necessity of inverters appeared to drive the compressor at a fixed speed. In this paper, we introduced the method of driving a large capacity, variable speed motor drive without using gas turbine. It has been paying attention from excellent operability and easy maintainability point of view as a drive system for the oncoming generation. In this paper, we introduce a 3-level GCT (Gate Commutated Turn-off) thyristor inverter application in the field for Oil and Gas Industry as a high speed, large capacity with high efficiency motor drive equipment. As the redundant control is adopted, the drive equipment with high reliability can be provided. An excellent result which was confirmed by applying this inverter equipment to a high-speed compressor is introduced.
