    Abstract

    An 8-bit digital gate driver (DGD) using a half-bridge digital-to-analog converter (HB DAC) IC and two power MOSFETs is proposed to enable the output voltage swing of ± 15 V and the large gate current up to 58 A for a 6500 V, 1000 A IGBT module. In the turn-on measurements of IGBT at 3000 V and 1000 A, compared with the conventional single-step gate driving, the proposed active gate driving using DGD reduces the switching loss from 6.9 J to 4.8 J by 30 % at the same current overshoot of 1.3 kA and reduces the current overshoot from 1560 A to 1330 A by 15 % at the same switching loss of 5 J, which clearly shows the advantage of DGD for the 6500 V, 1000 A IGBT module. This paper is the first to demonstrate the advantages of DGD in the high-voltage, large-current IGBT modules.
