The car power converter is a commonly used accessories for cars. It plays an important role in providing electricity in the electronic equipment in the car. The following is a comprehensive analysis of the vehicle power converter.
Functional principle
There are two main types of vehicle power converters. One is the DC/DC converter. Its role is to convert a DC power supply of a certain voltage level into a DC power supply at other voltage levels. For example, in new energy vehicles, DC/DC conversion conversion The device can convert high -voltage DC power to 14V or 28V low -voltage DC power for use of the vehicle's low -voltage electrical equipment, such as instrument, wiper, lights, audio and other equipment, and then charge small batteries. The other is the car inverter. Convert 12V DC electricity to 220V AC electricity, which can be used for general electrical appliances, such as car refrigerators, electric furnaces, electric tools, etc.
Application scenarios
Car power converter: When you need to use some conventional household AC electrical appliances in the car, the car inverter plays an important role. For example, in a long -distance trip, using the car inverter to connect the car in the refrigerator to keep the food fresh; In the outdoor operation, electric tools can be used through the car inverter. The DC/DC converter is the key to ensuring the normal operation of low -voltage electrical equipment in the vehicle. It can ensure the stable work of various instruments, lights and other equipment in the vehicle, and provide support for the normal driving of the vehicle.
Performance parameters
Car power converter: The power specifications of the vehicle inverter are diverse. The common ones are 20W, 40W, 80W, 120W until 150W, etc. Its input voltage is generally DC10V ~ 14.5V, the output voltage is AC200V ~ 220V ± 10%, the output frequency It is 50Hz ± 5%, and the conversion efficiency is greater than 85%. The power of the DC/DC converter depends on the needs of the vehicle's low -voltage system. Generally, it has high conversion efficiency and stability to meet the requirements of the vehicle's long -term operation.
Exterior design
Car power converter: The vehicle inverter is usually relatively large because it needs to have components such as control circuits, filter capacitors, cooling equipment, and power modules. In order to ensure heat dissipation and safety performance, the shell design is relatively thick. The DC/DC converter is generally designed according to the installation space of the vehicle, with different shapes and sizes, but it usually has good sealing and seismic resistance to adapt to various environments in the vehicle driving.
