The TRICONEX 2301 gate control circuit composed of integrated modules has been widely used due to its reliable performance and convenient use, and is also the development direction of driving circuits. Major companies have different series of IGBT driver modules, with similar basic functions and constantly improving control performance. For example, Fuji’s EXB series driver modules have optocouplers and overcurrent protection circuits inside, and their functions are shown in the following figure.
The external interface circuit between the TRICONEX 2301 series driver module and IGBT is shown in the following figure. The driving signal is amplified by an external transistor and input into the module through pins 14 and 15. The overcurrent protection signal is obtained by measuring the on state voltage vCE that reflects the current magnitude of the component, and then outputted by an external optocoupler device. When overcurrent occurs, the IGBT is immediately turned off. Two 33uF external capacitors are used to absorb changes in supply voltage caused by power wiring. The TRICONEX 2301 of pin 1 and pin 3 are respectively connected to the emitter E and gate G of the IGBT. The leads should be as short as possible and twisted wires should be used to reduce interference with the gate signal. D in the figure is a fast recovery diode.
