Influence of Parasitic Resistance of Inductor on Voltage Closed-loop Control of DC-DC Converter
Taking the Boost converter as an example,the voltage open-loop transfer function of the DC-DC converter(including parasitic resistance)is derived by the state space averaging method.On this basis,the voltage closed-loop transfer function of the converter is constructed.The dynamic perform-ance of the inductor parasitic resistance converter model and the ideal converter model under voltage closed-loop control is compared by using Matlab/Simulink simulation.
