Abstract
Solar energy is a new energy which is clean, efficient, and will never run out . Photovoltaic power generation is safe and reliable, it has no noise, no pollution, less constraints, low failure rate, it is easy maintenance, etc., so it has been widely used.
Solar power generation is used in the automotive, will be able to effectively reduce the global environmental pollution, and create the clean living environment. With the global economy and the rapid development of science and technology, solar energy industry as a motor vehicle is not a myth. Solar car uses the battery turning the light energy to the electrical energy, the electrical energy will be kept in the storage batteries, to drive the motor vehicles. Through the charging circuit, getting the required voltage of 12V DC for lights, speakers, etc. use; Using the DC / DC converter circuits which can achieve the 12V changing into 350V DC; at the same time, through the DC / AC converter, we can get the AC 220V,which can be used in the refrigerator, so as to achieve the purpose providing the electrical power to the car so . This article designs the storage charging circuit、DC / DC converter circuit and based on the SG3525 chip DC / AC converters will make full use of solar energy, it has momentous significance.
