Webwere optimized to reduce the overshoot to less than 20 V. This overshoot limit provided some margin to protect the FET, which had a 30-V maximum voltage rating. Figure 2 shows the overshoot for the baseline circuit and the reduced- ringing overshoot for the boot resistor, gate resistor, and snubber. The waveform for WebVoltage overshoot across the IGBT at turn off is defined by the total inductance in the loop comprised of the DC link capacitor, bus structure, and internal switch branches. The measurements presented here demonstrate that the external ESL contribution can be reduced to 15 nH, thus establishing a new low-ESL regime.
