| Abstract: | A non-ideal small signal model of Boost converter is established in the application of the energy conservation.Based on the circuit topology,a peak current mode control is introduced,and a more accurate equivalent power level circuit model is derived on the slope compensation.On the basic of the peak current mode Boost converter and considesed the defects of the circuit,and voltage control compensation network has designed to make the compensation system better stability.The results of the MATLAB software simulation show that the program binifits in use. |
