Abstract

This paper presents a control approach to regulate voltage slope and oscillation amplitude in a silicon carbide inverter during operation. Based on sensor measurements, the control adapts the switching characteristics using an adaptive gate driver and thus adjusts the level of voltage slopes, oscillation amplitude and consequently, electromagnetic emissions to a target level.
