Switching Power Supply Information Decision-making System

Power is the driving force of all electronic equipment, which have a lot of features forexample, power, noise, effect, voltage and other parameters vary.The same parameters of therequirements,the performance and indicators may differ. Designers can follow the differentrequirements to "mold" the power, so the form of the power in a wide range.High-frequency switching power supply is the devices that the voltage regulates power .Itbased on a high-frequency switch-mode DC power supply, which uses high frequencyswitching power devices and made of conversion technology and high-frequency switchingDC power supply.It is referred to as switching power . Switching power supply are mentionedbelow refers to the high-frequency switching power supply in the paper. At present, theswitching power supply is more widely applied because of its unique superiority. Now,theproduction process of the switching power supply , is designers use the traditional designmethods, which based on the basic principle of the circuit and its power output.That is basedon previous experimental data and power supply design experience to determine the design ofpower and the initial design. The initial prototype designed by experiment, and then correctethe parameters, until fullfill the performance and indicators. Because the designers experienceand subjective ,the decisions of switching power supply design is not optimal design.So wecan develope with the switching power supply optimization decision analysis software.Thatgives the optimization decisions of the switching power supply circuit design has importantpractical significance.The subject use power electronics, computer software, value engineering, operationsresearch and multi-disciplinary organic integration in the actual course of the study. Forexample the actual switching power supply program transit the various functions and circuitcosts to assort the necessarythe importance and score with the switching power supply powerfactor (PFC), voltage / current stress, loss, and efficiency. In order to determine the optimaldesign of individual value coefficient,we will choose and compare with the plan ,and decidethe optimal design of the combined value based on the individual value.The subject developed switching power supply information decision-making system toget the optimal design by the VC++ .The PSIM language to verify the optimality of thesystem power program through contrast waveform.It provides theoretical guidance for theactual high-frequency switching power supply design and development.
