Abstract:
This paper investigates a feasibility of an IGBT driver with current sources to obtain good trade-off between the switching loss and the output voltage overshoot. We consider here an employment of multiple-peak current mirror circuits for the current mode IGBT driver, which can control the current amount in time for pulling the charge from (turn-off case) and pushing one to (turn-on case) the IGBT gate capacitances. We have examined the IGBT turn-off case by pulling the charge from the IGBT gate capacitances, and SPICE simulation results show that our investigated IGBT driver with controlled current sources can achieve lower loss than the one with controlled voltage sources when keeping the overshoot voltage to be equal.
