| Abstract |
In this article, a double closed-loop self-regulating active gate driver (DCSAGD) for power device is proposed. The high-bandwidth peak detection circuit based on operational trans-conductance amplifier realize the accurate sampling of vDS\_peak in the ns-level turn-off process. The closed-loop control strategy is realized at low cost by all analog circuit. The experimental results show that the system can accurately control vDS\_peak at 500V/40A working condition under two reference voltage of 700V and 730V. |
