Coining The Term Inverter

The first power inverters were used to create DC power from AC power for industrial, commercial, and railway electrification. At the time, they weren't called inverters, but were known as rotary convertors. They created power in much the same way as today's generators create power, except with a system designed for producing DC current instead of AC current. They consisted of a DC generator, or dynamo, and a set of slip rings evenly spaced around the rotor's windings.

When spun, the dynamo would create an alternating current that would be rectified by a commuter, allowing DC current to be extracted. In essence, the DC power is separately generated from the AC power by using a synchronous converter.

If controlled correctly, a DC converter can also be set to run backward, using the DC power to create AC power. The name inverter was coined because, at the time, it was just a DC rotary converter running backward, or a inverted converter. It is believed that David Prince coined the term inverter.

In 1925, he published a paper in the GE Review entitled "The Inverter", which contained almost all of the vital elements in modern-day inverters. It was also the first known publication to use the term inverter in literature. By 1936, Prince's inverter became common terminology in technical publications around the world.

How Power Inverters Work


Go to top.

Power inverters are needed to convert direct current, like the kind that comes from a car into an alternating current that can be used by standard electronics. Early AC power inverters were electro-mechanical. DC power flowed from one end of a circuit that had an electromagnet attached to it. Once the current contacted the magnet, it would activate and pull a wire that was attached to a spring arm. This would force the wire to come in contact with the circuit, change the flow of the current from one side to another another side of the circuit. At the same time, this would cut the power from the electromagnet.

Once the magnet was released, its spring arm would snap back, allowing the current to begin flowing from the original side of the circuit once again. This would activate the magnet again and the process would repeat itself.

Modern-day inverters are doing essentially the same thing, but instead of using electromagnets and spring arms, they make use of semiconductors as switches. This eliminates the need for an arm to flip back and forth in order to alternate the current.

All alternating currents produce a sine wave of some form. AC in the home is a smooth, rounded sine wave, but many types of inverters create a squarish sine wave. This is fine for basic electronics, like coffee makers or blenders, but if running sensitive electronics that send and receive broadcasts of some kind, square sine waves can be problematic. For this reason, many modern inverters had a number of filters, capacitors, and inductors which are used to clean up the sine wave so it can be used by nearly any type of electronic device.

How To Select An Inverter


Go to top.

When selecting an inverter, the first step is matching the inverter to the voltage of the power source. If you will be using an inverter in with a car battery, you would need a 12-volt inverter as it will be drawing power from a car's 12-volt battery.

After identifying the correct voltage for your inverter, it is time to determine your power needs. To do this, you must have some idea of the electronics you want to power with the inverter. Look for a label on your devices that tells the required wattage. Your inverter must be able to produce at least this amount of wattage, preferably higher.

If you plan on powering multiple devices at the same time from your inverter, you need to add up the required wattage of all the devices. For example, if you have a coffeemaker that uses 600 watts, and you also plan on running a toaster oven at the same time which requires 1000 watts, you would need an inverter rated for a minimum of 1600 watts.

One must also take peak power into account. Some electronics use more power when starting up. This is known as the peak power rating. For example, a blender may be rated as using 600 watts, but have a peak or surge power rating of 800 watts. This means that it uses 800 watts at startup and then drops down to 600 while it is in operation. Most inverters also have a peak power rating that is higher than their operating wattage as they are designed to deal with this kind of load, but one should check the peak power rating of both devices first to ensure they are compatible.

Finally, one should look at the wave output. As we mentioned previously, inverters generally put out a square sine wave unless they have a number of filters and inductors incorporated to smooth out the wave. If you plan on using basic, non-audio and visual electronics, the wave output won't be as important, but if you want to be able to power a laptop or charge a smartphone, then an inverter with a "perfect sine" wave should be considered. These can be quite expensive though, so another option is an inverter with a modified sine wave. These will have enough filtering that they can generally be used with most electronics, but not perfectly rounded wave.

I love this power converter! It can swivel up to not take up tons of room in case straight outward would cover the cup holder like in my vehicle. It can hold in a three-prong plugins two USB cord chargers. Using all three at the same time does not short it or anything at all! I was impressed. It's very compact too for storage. Definitely getting my husband one for Christmas!

#8.Power Bright PW3500-12 Power Inverter 3500 Watt 12 Volt DC To 110 Volt AC


Does everything I need it to do. I put this in my semi truck, to run my microwave, hot plate, and t.v/DVD player, and it works great for that so far, the only thing I don't like about it is that the cord is a bit too short for the remote box, wish it was a little longer. But overall, very pleased.

#6.AUKEY 150W Power Inverter with Cup Holder Design & Outlet + USB Port for Laptop, Tablet, Smartphone and more


Working well so far. Used it during 2-hour car rides to charge cell phones and laptops; has not died. It is large and chunky as expected, but fits perfectly into the cup holder of our Acura TL. Quite a charge compared to the previous one we used where you can hear the fan and current.

#4.BESTEK 200W Power Inverter DC 12V to 110V AC Inverter with 4.2A 4-Port USB Car Adapter (MRI2011GU)


Excellent product. It makes a slight noise as the fan ensures the unit stays cool, however, that noise is drowned out by the car engine, road noise, and chatter inside the car. I thought about keeping it in a glove box but thought better of it as it would overheat and potentially break/and or cause damage to my car's electrical system.
