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). You probably won’t need a 2000 watt inverter, as this can be too powerful for a car. 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.
