设计了一种基于电压闭环的双路IGBT驱动电源,该驱动电源能够输出+15 V和-10 V两路电压,用于驱动IGBT的开通和关断。当输入电压低于-21 V时,通过反馈电路可将关断输出电压稳定在-6 V,保证IGBT可靠关断。最后,通过在Pspice软件中的仿真,验证了该电路的可行性和正确性。 A two-way IGBT driver based on voltage closed-loop is designed. The driving power supply can output two voltages of +15 V and -10 V to drive IGBT on and off. When the input voltage is lower than -21 V, the shutdown output voltage can be stabilized at -6 V by the feedback circuit to ensure reliable IGBT turn-off. Finally, through the simulation in Pspice software, the feasibility and correctness of this circuit are verified.
