Abstract
Disclosed herein is a gate-driving apparatus configured for stably providing a voltage having a negative value to a gate of a switch, including a SiC (silicon carbide)-based FET (Field Effect Transistor), which requires a negative voltage having a negative value to implement a stable OFF state. The gate-driving apparatus includes a negative-voltage application circuit including a Zener diode and a capacitor connected in parallel to the Zener diode, wherein the Zener diode may have a cathode connected to a secondary coil of a pulse transformer and an anode connected to the gate of the switch.
