What are the application fields of inverters?

1. The 220V electricity obtained by the car inverter is 220V 50HZ, the high-end ones are sine waves, and the cheap ones are generally square waves.
The sine wave type is the same as the electricity used on the socket, and the square wave type can actually be used, but if you use a fan and other equipment with a motor, there will be some noise. The reason why the square wave is used is The cost of this modulation method is relatively low. Generally, the maximum power of this vehicle-mounted inverter is no more than 500 watts, and the air conditioner is generally more than 700 watts. The air conditioners in cars, including those in buses, let the engine directly drive the compressor instead of using electricity. If there is an additional electric conversion process in the middle, the loss will be even greater. And it's not easy to install, it's better to use car air conditioners.
2. Connect to laptops, TVs, disc players, etc., as long as they are used at their rated power, there is no problem, but you need to pay attention to it is connected to the car battery, although it is usually 11V, it will automatically protect it from power failure. Avoid the low voltage causing the car to fail to start, but it is still not suitable for use when the engine is not running, so if the load is relatively large, it is recommended to start the engine. If it is to charge the phone, there is no problem.
3. On electric vehicles, there is a module called DC-DC, which is also called a DC converter. This module inputs 48V and outputs 12V, so you only need to buy a 12V input car inverter to use it. Of course, if you can buy a 48V input inverter, it is better, but it is estimated that it is difficult to buy. Moreover, this module generally can only provide 5A current, at most 10A, and also use car lights and other things, so it is easy to overload.
