How Power Inverter Works

Today, electronic gadgets are very often found in the cars and they are often powered by cigarette lighter as what popularly know as power port

. However, as the devices get more complex and numerous, there is often a need for more elaborate device that cannot be plugged into the cigarette lighter port. The devices like LCD TV's, Laptops are those examples. These devices can be powered up using a DC to AC power inverters. Power inverters can convert direct current that produced by the battery of the car into AC(Alternating Current) that powers most of the house hold appliances.

Cars and motor homes these days typically receive their power from a 12 volt battery; however this is not always the case. Before purchasing a power inverter, it is crucial that you know your vehicles voltage so you can buy the appropriate model. Car batteries produce what is known as DC energy, or direct current. This energy flows constantly from the negative terminal, completes the circuit, and then flows into the positive terminal. Because the power only flows in a single direction it is known as direct current.

Direct current energy is useful, but most appliances cannot use it. This is where power inverters come into play,power inverter used to power most appliances with a car battery. Power Inverters arent just used for automobiles however; another popular use for them is to convert the DC power produced by solar panels. There are even grid tie inverters which feed the power into the electrical power grid which can then be sold to power companies for a profit.

So, just how do DC to AC power inverters work? This can be a complicated process so to best understand it you should first view a 12v inverter circuit diagram. In the past, these devices worked by using an electromagnet. When the direct current energy would hit this magnet it would activate, pulling a wire to come in contact with the circuit. These devices have come a long way in recent decades however, and the most modern varieties typically use oscillator circuits to basically complete the same process. This is only a brief overview of a very complicated process which uses sine waves and square waves to create an alternating current.

When you are in the market for DC to AC power inverters the first step is to make sure you purchase a converter that matches the voltage of the vehicles battery. Next, take into consideration which devices you plan on using. Each device should tell you on the box how much wattage it requires in order to use it.
