摘　　要：为提高软启动电路平滑过渡控制的稳定性,提出一种基于电压自均衡直接耦合抗电感干扰的软启动电路平滑过渡控制方法。采用子模块串联支撑调节方法调节软启动电路的等交直流变换稳态性,并构建软启动电路的模块化多电平控制结构模型,根据模型提取系统的扰动数据,将模型结合直流最大可控功率调制方法设计抗电感干扰电路。通过电压自均衡直接耦合调节,避免系统发生暂态能量变化;对软启动电路平滑过渡进行控制,以抑制软启动电路的超低频振荡,完成软启动电路的平滑过渡控制。仿真结果表明,采用上述方法进行软启动电路平滑过渡控制的稳定性好,电路系统的振荡抑制能力较强,提高了抗电感干扰能力。In order to improve the stability of smooth transition control of soft-start circuit,this paper focuses on a method of smooth transition control for soft-start circuit of anti-inductance interference based on voltage self-balancing direct coupling.The support and regulation method of sub module series connection was used to regulate the stability of equal AC/DC conversion of soft-start circuit.The modularized multilevel control structure model of soft-start circuit was built.According to the disturbance data of extraction system,the model was combined with the DC maximum controllable power modulation method to design the anti-inductance interference circuit.Through the direct coupling regulation of voltage self-equalization,the change of transient energy of system was avoided.Finally,the smooth transition of soft-start circuit was controlled to restrain the ultra-low frequency oscillation of soft-start circuit and thus to complete the smooth transition control for soft-start circuit.Simulation results show that the proposed method has good stability of smooth transition control of soft-start circuit,strong oscillation suppression ability of circuit system,and improved ability of resisting inductance interference is.
