With the continuous development of the times,technology has become more and more developed,especially in the computer technology and Internet technology as the representative of the advanced technology is to achieve a leap-forward development.Not only that,but also gave birth to a lot of new information technology,including large data technology,cloud technology is one of the typical representative.It is no exaggeration to say that the development of the future era will gradually tend to large data age,in this case,many companies find one of the business opportunities,began to gradually shift the focus of the development of the cloud business.But here we need to focus on the need to efficiently and quickly host the cloud business,the first and most important thing is to have a standardized room,because only by virtue of the perfect hardware facilities,to carry out related business development.But to create a perfect standard room,the power can be said to be one of the indispensable equipment,because to some extent,these devices are all electrical equipment,leaving the power supply will not work properly.In addition,in order to ensure the safe and stable operation of the system,the requirements for the power supply more and more harsh,the traditional power supply has been unable to meet the needs of the market,so much-needed,in order to ensure that the system is safe and stable operation The emergence of a new type of power supply,in this case,UPS power(uninterruptible power supply)will be applied and born,and once launched,it has been the industry experts and scholars of the widespread concern,to achieve rapid development.Now with the continuous development of the times,standardized room for the power requirements are getting higher and higher,so based on the above background,with excellent performance,high-frequency UPS power supply gradually welcomed by the market.However,have to admit that this power supply there are some shortcomings and shortcomings,which is mainly reflected in the existence of a certain amount of harmonics.Therefore,in order to be foolproof,it is necessary to carry out harmonic processing work,with a view to effectively improve and improve the input side of the harmonic factor.But because of the impact of various factors,before almost no business and personal charger on the implementation of targeted power factor correction processing.Based on the above background,this graduation design mainly elaborated on the current several commonly used charger line,and on this basis,to build a new charger line,in order to eliminate the charger harmonics,and thus to ensure system security Stable operation.This graduation design mainly explores the new charger built on the basis of BUCK architecture.This type of charging device can realize double BUCK charging circuit with single inductance.On the charger line,mainly composed of positive and negative parts,but here need to emphasize that these two parts are also overlapping parts.Its most notable feature is the ability to integrate UPS systems to achieve line adjustment.In addition,the entire line structure is relatively simple,and easy to control,low cost,high performance,wide range of applications,so has a broad development space.The graduation design mainly explores the internal structure of the UPS system.At the same time,it elaborates the related characteristics and working principle of each function module,and also analyzes the advantages and disadvantages of the different architectures.Finally,the characteristics and working principle of the new charger are expounded in detail,and the hardware performance and software performance of the new charger are tested.The results show that the new charger circuit can improve the data of the UPS system and fully meet the actual needs of the market.
