With the rapid development of modern science and technology, power adapters, as a new type of regulated power supply, are used more and more widely, including not only power supply for meters, measurement systems and computer systems, but also widely used in various consumer electronic products, power adapters It has outstanding characteristics such as high efficiency, low power consumption, small size and light weight.
Power adapter technology is widely used. In just a few decades, it has been widely used in various industries in human society, and has played a positive role in promoting scientific and technological progress and productivity development in human society. The following are some common applications. Independent photovoltaic power generation, also known as off-grid photovoltaic power generation, is mainly composed of solar cell components, controllers and batteries, as shown in Figure 1-1. In order to supply power to the AC load, an AC inverter must also be configured. Independent photovoltaic power plants include village power supply systems in remote areas, solar home power supply systems, communication signal power supplies, cathodic protection, solar street lights and other battery-operated photovoltaic power generation systems.
In traditional industries such as banking, power, and chemical industries, uninterruptible power supplies (UPS) are mainly used to prevent data loss during sudden power outages and maintain stable operation of equipment.
A computer power supply is a device that converts 220V alternating current into direct current and supplies power to computer accessories (such as motherboards, drivers, graphics cards, etc.). ) It is the hub of power supply for computer components and an important part of the computer.
An electric vehicle (BEV) is a vehicle powered by an on-board power supply and driven by an electric motor, which meets the requirements of road traffic and safety regulations. Compared with traditional cars, it has less impact on the environment, so its prospects are widely optimistic, but the current technology is not yet mature. Working principle: battery-current-power regulator-motor-power transmission system-drive the car on the road. Compared with fuel vehicles, pure electric vehicles are mainly different from four major components: drive motor, speed controller, power battery and vehicle charger. Compared with gas stations, it has a public super fast charging station. The quality difference of pure electric vehicles depends on these four components, and its value also depends on the quality of these four components. The use of pure electric vehicles is also directly related to the selection and configuration of the four major components.
