摘　　要：利用状态空间平均法对非理想Boost变换器进行分析,建立控制到输出的数学模型。为了消去控制到输出的数学模型中S右半平面的零点,改善整个非理想Boost变换器的动态性能和静态性能,在补偿网络中设计了惯性环节进行补偿。为了验证设计的惯性补偿环节的准确性,进行仿真和样机测试验证,结果表明控制系统中设计的惯性补偿环节能够有效改善非理想Boost变换器的性能,使得非理想Boost变换器动态和静态性能良好。By using state space average method,mathematical model of control to output of non-ideal Boost converter was established.In order to eliminate zero point on right half plane of S in mathematical model of control to output,to improve dynamic and static performance of whole non-ideal Boost converter,inertial link was designed in compensation network to compensate.To test designed inertial link compensation network,simulation analysis and prototype test were done.Performance of non-ideal Boost converter was improved by designed inertial link compensation network was showed in result.Non-ideal Boost converter is with good dynamic and static performance.
