摘要
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 dual-channel IGBT drive power based on voltage negative feedback control is presented. This power circuit provides dualchannel output, 15 V and -10 V, which are used to turn on and turn off the IGBT. The 15 V voltage is regulated to maintain stable regardless of the output power level, and the turn-off voltage is regulated to -6 V, while the input power is less than -21V. Finally, Pspice simulation software is used to verify its feasibility and correctness.
