Research On Photovoltaic Air Condtioner Control System Of Time-varying And Constrained Power Conditioner

The rapid economic development has accelerated the exploitation of fossil fuels,fossil fuels are formed over millions of years. over-exploitation of fossil fuels makes themankind facing a serious energy crisis. New energy development and utilization hasbecome a hot issue today. Solar energy is one of the important new energy and widelydistributed, inexhaustible inexhaustible and pollution-free. It is an ideal alternativeenergy sources. Now, solar energy products can be seen everywhere in human life, solarair conditioning is one of them.There are two methods to realize solar air conditioning: First is light-heat transfertechnology, and the other light-electricity conversion technology. Using light-heatingtechnology for solar air conditioning is mainly used in centeral air conditioning system,air conditioning system is used rarely and not conductive to home users. Light–electricity conversion is through the solar power Grid-connected or add batteries toachieve. the bottleneck of PV air conditioning into the family is: First, the costs are toohigh; Second,battery life and it brings secondary pollution;Third, ineffective use.To solve the above problem in this article a new type of solar air conditioningsystem is proposed, powered entirely by solar power supply mode, neithergrid-connected also not batteries, based on power electronic technology limited, thesolar the time-varying power, effectively used for air conditioner motor drive, how weuse much solar energy solar energy purpose. The basic idea of this subject is: DC outputof the solar cell maximum power point tracking technology output and boost; detectionand calculation of the solar cell power to determine the size of a given frequency power,given the corresponding control the signal boost after the DC after IPM inverse to thecorresponding frequency, voltage AC supply air-conditioning motors; controller chip theSunplus SPMC75F2413A microcontroller.Modeling and simulation systems in the MATLAB/SIMULINK environment andthe ideal simulation waveforms, and the system part of the hardware circuit design.
