Abstract The negative voltage generated by right-half-plane zero results in poor transient performance of the Boost converter working in wide input voltage range and wide load range. Therefore, an effective negative voltage suppression is the key to improve transient performance. This paper builds a mathematical model for negative voltage of the Boost converter working at wide input voltage range and load full dynamic range. The performance indicators of negative voltage evaluation and the constraint condition of suppression are provided. According to the results of modeling, a parameter optimization design method based on decreasing the system damping ratio is proposed to improve the transient performance. The simulation and experimental results have verified the negative voltage modeling within the full dynamic range and the proposed method of parameter optimization design. It provides an effective way to improve the transient performance of Boost converter working in wide input voltage range and wide load range.

Key words： Boost converter full dynamic range negative voltage transient performance damping ratio
