Soft-Start Circuit Smooth Transition Control Simulation of Anti-Inductance Interference

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.
