Nowadays, many people use a car for long-distance travel and even sleep in it. They often need to charge a phone, laptop, and some other devices but cannot do it due to the lack of an appropriate voltage power supply. In this case, a car inverter can help. This appliance is able to convert the voltage of the car into that required for a particular device.
How Do Car Inverters Work?
A car power inverter is a device that converts the DC voltage of a power supply into an AC voltage. Basically, a car inverter is an opposite device to a rectifier (converts AC to DC) that converts the 12-volt voltage of a car battery into a 220-volt voltage capable of powering consumer electronics and providing a 50 Hz output. Inverters connect to the battery and make life on the road much easier
There are inverters that can be connected to a cigarette lighter (with a power of no more than 150 W). And there are those that need to be connected only directly to the battery (with a power of more than 150 W). The main thing to observe when connecting is polarity.
The main thing to observe when connecting is polarity. The car inverter is based on semiconductors. It has a metal or plastic case, on which, on one side, there are terminals for connecting to a battery (or a plug for a cigarette lighter), and on the other side – ordinary sockets where you can connect household appliances.
A modern high-quality inverter is equipped with a system that protects electrical appliances and the inverter itself from damage that could arise due to improper connection of appliances to the inverter or too low/high input voltage.
