With ever-rising concerns about saving of fossil fuel resource, there have also been an increasing demand for using of energy more efficiently. The electric motor driven inverters can be a great help to improve energy efficiency. They are used to control the motor speed to the actual need. Therefore the use of them can lead to reduce energy consumption. In particular, the medium voltage(MV) drive systems which are used for pumps, fans, steel rolling mills and tractions have widespread applications in the industry. They covers power ratings from 0.4MW to 40MW at the medium-voltage level of 2.3kV to 13.8kV. However, the majority of the installed MV drive systems are in the 1MW to 4MW range with voltage rating from 3.3kV to 6.6kV. Recently, they also have been required to reduce size and weight like other power electronic equipments. In this paper, we studied on the 3.3kV(105A) compact rack type inverter system for improving of cooling efficiency. At first, we confirmed the tendency of temperature to compare with computational simulation using ANSYS ICEPAK and actual experimental tests. And then we researched thermal performance improvement designs in order to reduce temperature of the transformer for the safe operation. As a result, we found out more efficient solution by thermal-fluid analysis.

Therefore the use of them can lead to reduce energy consumption. In particular, the medium voltage(MV) drive systems used for pumps, fans, steel rolling mills and tractions have widespread applications in the industry. They cover power ratings from 0.4㎿ to 40㎿ at the ㎹ level of 2.3㎸ to 13.8㎸. The majority of the installed MV drive systems however, are in the 1㎿ to 4㎿ range with voltage rating from 3.3㎸ to 6.6㎸. But they are required to reduce size and weight like other power electronic equipments. In this paper, we studied on the 3.3㎸(105A) compact rack type inverter system for improving the cooling efficiency.

It can reduce temperature of transformer that using pipe type flow guide in the system. As a result, we found out more efficient solution by thermal-fluid analysis.
