[0019] In order to further reveal the technical solution of the present invention, the following describes the embodiments of the present invention in detail with reference to the accompanying drawings: figure 1 As shown, a compact IGBT module drive unit is divided into three parts from the structural design: a power supply board, a drive core board and a module adapter board. The power of the entire drive unit is taken from the high-voltage bus of the entire main circuit, and then converted into the voltage required by the drive core board, and provided to the drive circuit; the protection control circuits required by all types of IGBTs are set on the drive core board; Different module adapter boards are designed for different types of modules. The drive circuits are all set on the adapter board. The entire drive unit is composed of "power board + drive core board + module adapter board", with cables or connections in the middle. The terminals are connected to achieve the goal ...
