Abstract:
The drive circuit is one of the key circuits for the successful application of IGBT, and its localization, digital intelligence, safety and reliability are crucial under the current global energy technology revolution. However, the current domestic IGBT drive products, on the one hand, there is a lack of flexibility in the drive function, digitalization, intelligence, on the other hand, there is still room for improvement in the degree of localization. Therefore, aiming at the above problems, the localization intelligent IGBT driver circuit based on FPGA is proposed, which improves the digitalization and intelligence of the driver circuit through the combination of software and hardware. Considering the function of the drive circuit from the practical application scenario, the design and implementation of the control signal narrow pulse suppression, error control signal monitoring, working mode diversity selection, over-current and over-voltage fault monitoring protection, fault type identification and feedback. At the same time, all the electronic components used in the design are domestic, which meets the requirements of independent controllability. Finally, the designed circuit is manufactured and the parameters and functions are tested. The results show that the drive circuit designed based on the domestic device can realize the expected functions and
