Green energy, also known as clean energy, is the symbol and pronoun of environmental protection and good ecosystem.
It can be divided into two concepts: narrow sense and broad sense.
In a narrow sense, green energy refers to renewable energy, such as water energy, biological energy, solar energy, wind energy, geothermal energy and ocean energy. The energy consumed can then be replaced with little pollution.
In the broad sense, green energy includes the selection of energy with low or no pollution to the ecological environment, such as natural gas, clean coal and nuclear energy, in the process of energy production and consumption.
Solar photovoltaic is the cleanest and most abundant source of energy available to us The solar cell power generation system installed on the roof and wall of the building can directly convert the solar radiation energy into electric energy, use the battery bank to store the electric energy generated by the solar cell under the light, and can supply power to the electrical equipment at any time, so as to meet the power demand of the building’s power and lighting system. Solar cell power generation technology has many advantages, such as safe and reliable, no pollution, no consumption of conventional fuel, not restricted by the region, easy maintenance, suitable for installation on buildings, etc., it is the most promising new energy utilization technology in the world today.
Improving conversion efficiency is an important part of optimizing power system performance and realizing “throttling”
The efficiency of AC/DC adapter is not only related to the raw material itself, but also related to the complexity of the design and design skills. The conversion efficiency can be effectively improved by selecting the appropriate working mode according to the specific power application requirements, optimizing the selection of materials and adopting common design techniques. In addition to the use of low loss devices, the performance of AC/DC adapters can be mainly improved by resonant conversion, synchronous rectification and other technologies. The efficiency can also be improved by new PFC structures, such as bridgeless PFC and staggered PFC. Interlaced PFC controller can help designers simplify power supply design, improve system reliability, and achieve higher power factor and rated efficiency.
