IGBT TRANSISTOR CONTROL METHOD AND RELATED CONTROLLER

摘要

PROBLEM TO BE SOLVED: To implement an IGBT transistor control method and related controller that enable effective control of an intermediate step in switching a transistor between an OFF state and ON state, without making a structure of an electric circuit related to the transistor more complex.;SOLUTION: This method for controlling an IGBT transistor (14) includes a phase for switching the transistor (14) between an ON state and OFF state. The phase includes generating setting value current taking different setting values of strength on a gate of the transistor (14). At least some of the setting values are selected depending on a sign of a time derivative of principal current. The respective setting values are selected from a set of predetermined setting values.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
