In this paper, a new IGBT driver design scheme is proposed for the design problem of the IGBT driver in NPC three-level inverter. Based on the performance requirements of the IGBT driver, this paper adopts the design scheme of isolated power supply, positive voltage turn-on, and negative voltage turn-off. This paper focuses on the design process of the power supply part and the driver part and an experimental prototype is designed based on the calculated data. In the experimental prototype to test the power supply part of the efficiency, ripple, and drive the actual output of the drive waveforms, experimental data show that the designed IGBT driver drive performance is excellent and meets the design requirements.
