摘要：Based on the energy conservation method and the average modeling method of switching elements, considering the non-ideal parameters of the actual circuit, the whole peak current mode control non-ideal Buck converter system model is established. On this basis, for the equivalent power level, there are still some problems such as slow response speed and poor stability. A voltage controller compensation method is proposed and a system model including voltage controller compensation network is established. Through the analysis of the model and the simulation in Matlab, it can be seen that the model is intuitive and clear in physical meaning, which can more accurately reflect the working condition of the actual circuit. The designed voltage controller can improve the performance of the converter and can be DC-DC. The design of the converter system control circuit provides a theoretical basis.
