Study on Current-Driven IGBT Driver Circuit

This paper studies a current-driven IGBT driver circuit to reduce the collector voltage overshoot and switching loss during its turn-off. The gate voltage operating region is divided into 4 and for each region, the optimal amount of the pulling current from the IGBT gate is used. Our simulations show that with the current-driven IGBT driver, the overshoot voltage is reduced by 31 % and the switching loss is by 35%, compared to the voltage-driven IGBT driver usage case.
