How Does a Power Inverter Work?
A power inverter takes up the power from a car’s battery and converts this direct current to alternating current. It does so because all the various appliances that run in a household run on alternating current.
Large electronics also run on alternating current. Thus, a power inverter converts DC into AC and enables you to run all appliances hassle free.
The power inverter is what does the work of this converter. It can be used to run various electrical appliances by connecting the inverter to the car and the appliances to the inverter.
Most of the electronics that we use at home require a pure sine wave, thus many inverters have added features that create pure sine waves.
What is a Power Inverter for a Car?
There are different types of inverters that are used to function in a car.
The two main kinds from among them are modified sine wave and pure sine wave inverters.
As the name suggests, modified sine wave inverters produce modified sine waves.
This type of inverters tries to clone pure sine waves by making the voltage go straight up and down.
These are mostly suitable for running simple household electronic items. For delicate medical equipment and upscale sound systems, you should opt for a pure sine wave inverter.
On the other hand, pure sine waves produce sine waves that are closer to the alternating current produced at home. There are numerous gadgets that need a continuous power supply.
LED TVs, audio systems, medical equipment work to their maximum efficiency on pure sine wave.
How Do You Convert AC to DC?
The work of converting alternating current to direct current is done by a rectifier. The easiest way to convert AC to DC is to use diodes.
Diodes are devices that allow current to pass easily from positive to negative terminals but not so easily from negative to positive terminals.
Even though the bridge rectifier has converted the AC to DC, the resulting current is not a steady voltage. Due to too many ripples in this resulting direct current, the circuit can malfunction.
Therefore, this resulting DC needs to be further filtered in order to make it steady.
For this purpose, two kinds of rectifiers can be used- half-wave rectifiers and full wave rectifiers. The former uses only one diode.
It is so called because it allows the passage of only half of the AC current. These are simple to construct.
How Long Can You Run an Inverter on a Car Battery?
How long your inverter can run on a car battery depends on two things- how much power you are using and what the capacity of your battery is.
(10 x (Battery capacity)/ Load)/2
This formula will give you the length that your inverter can run on the car battery.
How Long Does a Power Inverter Last?
As already mentioned, how long your power inverter lasts depends on how much load you are attaching to the inverter.
If you use the entire wattage of the battery at once, then dividing the wattage of the load attached by the voltage of the battery will give tell you how long the inverter will last.
Keep in mind that if you follow this method, the result that you get will be very less number of hours depending on the capacity of the battery.
However, that is so only because here, our load voltage is equal to the battery capacity.
Can I Use a Car Battery for the Inverter?
We can definitely use car batteries to power the inverter.
However, car batteries are designed for light operations and needs to be kept full most of the time.
Using a car battery for an inverter means draining it with a considerable amount.
This is usually not suggested.
Deep cycle batteries are a better choice as they guarantee longer life cycles.
But you need to be aware of the fact that lead-acid batteries are not sealed, there are chances that the acid might spill.
Do Car Inverters Drain Battery?
Whether car inverters drain the battery or not will depend on whether the engine is running. If the vehicle is being driven or the engine is kept running, then the inverter will not drain the battery.
So, it is better to stop using the inverter before shutting down the engine or always keep a deep cycle battery as a backup.
How Many Amps Does a Power Inverter Draw?
To find out how much power an inverter draws you simply need to divide the load watts by 20. This will provide you with a number of amperes that a power inverter draws.
The Bottom Line
Blessed are the creators of power inverters who provided us with instant relief systems during emergent situations. There are various brands that will provide you with various features.
So, make a list of features that you will need in an inverter and then make your choice. If I were to suggest an inverter, I would at once, go for PEAK 3000W.
However, if you want to go for a smaller and easily portable inverter, then KRIËGER 1100-Watt is what you should pick.
In the end, the best power inverter for you depends on your needs, so choose wisely and drop me a comment, if anything.
