【Abstract】 The process of the IGBT switching communication and the effect of the gate drive parameters on the switching process were analyzed, based on the equivalent active model. Also the IGBT driver’s design principle and the technique, including the signal transmission, isolated power supply, drive output and protection were introduced in detail. The differences of output characteristics, the merits and demerits because of the different design method were summarized. The TX-2DE300M17, 2SC0435 and 2QD15A17K-C were used to design the driver circuit and do the double pulse testing experiment to the Infineon FF300R17KE4. The waveforms of turn-on were compared and the three driver technology’s differences, advantages and disadvantages were analyzed.更多还原
