Popis: | This paper demonstrates the voltage balancing performance and switching behavior of four series-connected SiC MOSFET devices. Both multilevel and two-level topologies are capable of achieving higher blocking voltages in high-power converter applications. Compared to multilevel topologies, twolevel switching topologies are of interest due to less complex circuitry, higher density, and simpler control techniques. In order to balance the voltage between series-connected MOSFETs, device turn-off speeds are dynamically controlled on each gate-driver with active gate control. The implementation of the active gate control technique is described in this paper. Experimental results of the voltage balancing behavior across four non-commercial 1.7 kV SiC MOSFET devices in series (2 kV total dc bus voltage) with the selected active dv/dt control scheme are shown. |
