摘要:
为了分析恒功率负载对直流变换器稳定性能的影响，以恒功率负载的产生机理为切入点，并将Boost变换器作为研究对象，采用状态空间平均法，搭建带恒功率负载的Boost变换器模型。伯德图和仿真结果皆表明，恒功率负载会使Boost变换器不稳定。
Abstract:
The paper analyzes the effect of constant power load on the system stability performance.Taking the generation mechanism of constant power load as the starting point,and regarding Boost converter as the research object,it builds the Boost converter model with constant power load by the state space averaging method.Finally,the simulation tests verify that the Boost converter system is unstable when feeding constant power load.The Bode diagrams and simulation results show that the constant power load oscillates the output voltage of the Boost converter,making the system unstable.
