A voltage … pcyc hiltonWebWith a large gate drive current, high switching speed and low switching losses can be achieved in a power converter. However, a high current/voltage overshoot occurs. To solve this problem, a feedback current proportional to the di/dt or dv/dt signal is generated to the IGBT gate. Thus, direct control of the net gate drive current is produced. pcyc homebush addressWebMOSFET or IGBT's internal gate resistance is large enough. Figure 4.
