Research On Interleaved High Gain Boost Converter With Magnetic Integrated Switch Inductor

With the increasing depletion of energy,all countries in the world have the use of new energy and storage as the important development direction of industry,excessive dependence on oil and other fossil fuels,environmental pollution and other issues,caused people to new energy research and development boom.The development and utilization of clean energy as a clean energy choice is imminent.The wind and solar energy have aroused the concern of scholars,it is inexhaustible,inexhaustible characteristics.In the energy storage system,DC/DC converter undertakes the energy transfer mission,so DC/DC converter as the energy conversion device is particularly important.In order to improve the voltage gain of the traditional Boost converter,the volume and weight of the current ripple and converter transient response speed and decreasing the inductance branch,the magnetic integration technique,the interleaving technique and the switch inductance and capacitor is applied to the traditional Boost in the integrated magnetic switch inductor interleaved high gain Boost converter.The switch inductance structure replace traditional Boost converter can improve the voltage gain of the converter,but due to certain situations,in order to further improve the gain,this paper introduces the energy storage capacitor unit,the reference voltage gain switch inductance and energy storage capacitor converter can make the proposed increase 2 times the traditional Boost converter.The magnetic integration technique and reasonable design of coupled inductor current ripple coefficient can not only reduce the converter power branch inductance,but also can improve the system transient response speed,reduce the weight of the converter,so as to improve the electrical performance of the converter.By using the method of equivalent inductance is given a normalized design criterion of the converter inductance coupling using state space average method to model the converter,to derive the transfer function and the stability of system demands the corresponding controller is designed,and the parameters are designed.Through simulation and experiment verify the above proposed interleaved integrated magnetic switch inductance and high gain Boost transform The device has better electrical performance.
