Abstract：The high-power IGBT is a key component in the medium-high voltage and large-capacity power electronic converter system, while the gate drive technology is a critical factor influencing the performance of IGBT devices and converter system. This paper theoretically analyzed the IGBT gate drive control technology, proposed an open-loop hierarchical drive scheme, and designed a specific digital drive circuit based on the FPGA. The comparisons of the designed driver with the Concept driver through experiments show that the designed driver can effectively reduce switching delay time without degrading other parameters (reverse recovery current, turn-off overvoltage, diC/dt, dvCE/dt).
