The Balanced Compensation Of Solar Cells Based On The Flyback Inverter

From the analysis of the current situation of energy,solar power is the main trend of future energy.Solar energy is a kind of new clean energy,it has the advantage that the inexhaustible,therefore the study of solar cells is necessary.The focus of the research content of this paper is mainly for PV panels covered issues and using appropriate balance compensation circuit to increase the output efficiency of energy.This paper uses the mathematical model of the PV modules for the simulation of the project,and set up in the PSIM simulation model,simulate the output characteristics of PV array.As is known to all,the shade of the shelter,the existence of the dust,will cause the cover of the solar cell.When in series with the PV array to cover situation,will cause the loss of the whole series of the output power of PV panels,and the peak phenomenon,at the same time it will have a big impact on the output efficiency of PV panels.This thesis first shelter of PV panels is carried on the detailed analysis,to find shelter problem causing the output power down of PV panels,and then put forward using the principle of the Flyback converter to realize balanced analysis,it presents a design method of the circuit,the parameter design of the Flyback converter in detail,at the same time,it sets up the small signal modeling and design of the controller.And the principle of the maximum power point tracking MPPT and design.It uses PSIM simulation,at the same time makes The Flyback converter balanced prototype.This paper adopts the DSP control,using the specific TMS320F28335 chip is TI manufacturer,to complete the program in the DSP control.Finally,debugging prototype,according to waveform figure verify the feasibility.The paper adopts Flyback circuit is not only simple but also easy to implement,and the cost is low.At the same time it solves the problem of the peak and power reduction.It meets the requirements and realizes the function.
