Effects of Two-Level Turn-Off on Silicon Carbide Module Performance

Switching an SiC MOSFET Power Module creates two significant problems that need to be addressed to optimize the performance of the device: turn-off spikes and ringing. These two parasitic problems need to be controlled while maintaining efficient switching.

AgileSwitch has developed a patent-pending line of programmable Gate Drive Boards (GDBs) that address these problems, controlling the turn-off di/dt by varying the gate voltage level and dwell time to an intermediate level during turn-off. This process is typically referred to as Two-Level Turn-Off or 2LTO, while having more than one intermediate step is referred to as Multi-Level Turn-Off or MLTO.

In addition, AgileSwitch software configurable GDBs report out 7 unique fault conditions along with Temperature and DC Link Voltage. The combination of these effects will help drive growth in adoption of SiC devices, and the inverters that they support.
