title = "Design of an advanced programmable current-source gate driver for dynamic control of SiC device",
abstract = "Silicon carbide (SiC) power devices outperform Silicon-based devices in operational voltage levels, power densities, operational temperatures and switching frequencies. However, the gate oxide of SiC-based device is more fragile compared with its Si counterpart. The vulnerability of the gate oxide in SiC power devices requires the development of a gate driver that is able to have more control during the turn-on and turn-off process. This paper proposes an innovative current-source gate driver where the gate current can be fully programmed. The novelty of the gate driver is that the dynamic switching transients and the static on/off-state can be controlled independently. In order to achieve this approach, a signal decomposition and reconstruction technique is proposed to apply the separate control over the dynamic switching transient and the static on/off-state gate voltage respectively. The fundamental principle of the proposed circuit is verified in simulation. In addition, a prototype of the active gate driver has been built and tested to validate the effectiveness of the flexible control over the gate voltage.",
