Type Selection and Design of Drive and Protection of Power Device of Mine-used Frequency Converter

The paper analyzed requiements of underground devices for power device IGBT of frequency converter and electrical parameters which should be considered in type selection of IGBT, and designed a drive and protection circuit of IGBT by use of 2SD315 module. The actual application showed that frequency converter is stable in running and effective in IGBT drive with perfect protection after using selected IGBT and designed drive and protection circuit by use of methods described in the paper.
