Research On The Master Salve Control Of DC Micrgrid Connected To Dual-port Converter

This paper mainly discusses the basic principle of controlling the solar panel micro inverter driver chip based on the structure and design process,the simulation of the designed circuit by using the simulation tool software,verify the feasibility of the circuit.The micro inverter is designed in this paper is 220 V and the frequency of 50 HZ sine wave.In the design,we adopt SPWM inverter technology,AT89C51 MCU control SA4828 chip SPWM wave output,the drive module drives the MOSFET voltage type inverter circuit of the switching element from the reverse DC voltage into AC voltage stability.In this paper,we first analyze and design of the main circuit,and then use the programming of SA4828 three-phase SPWM wave generator are introduced,the boost and inverter circuit are introduced.In addition,we also discuss the MOSFET driver circuit,detection circuit,the display circuit,and analyzes the software design process the system.The simulation and test system using MATLAB simulation software,the main circuit part of the system,the control part and the measurement part of simulation and analysis of the experimental results,the stability of the test system,the accuracy of parameter selection.
