An inverter generator is a device that uses an internally located combustion engine, an alternator and a DC-AC converter to power up electronic gadgets. These devices are increasingly becoming popular in the country due to their high efficiency, ability to reduce emissions, noise, and the fact that they minimize fuel consumption. Inverter generators work in two simple steps. They first produce DC power and then convert it into alternating current through a microprocessor controlled inverter. Additionally, the production of DC energy is produced as soon as the engine starts powering the machine up, thus lowering the voltage. Low voltage results in reduced power consumption. On the other hand, inverter generators run at a constant speed, which not only leads to cleaner power but also reduces noise pollution.

What is an Inverter?

It is an electronic device that converts direct currents from generators, batteries and other fuel cells into alternating currents. Inverters work depending on several factors, the input voltage, output voltage and power handling ability. They do not produce any power, but only convert power from DC sources into alternating current. An inverter can either be electronically made or be a combination of rotary apparatus and electronic circuitry. Below are some of the components of a normal operator.

• Input Voltage

  The input voltage of an inverter depends on the design and use of the device itself. There are several examples of input voltage used in several machines and gadgets. A normal 12v lead acid battery, for example, supports a 12VDC input voltage while the input voltage for an electric vehicle battery ranges from 300 to 450 VDC. The input voltage can go up in the thousands if the inverter is part of a high current DC system.

• Output voltage

  Depending on the type of inverter in question, AC current may be produced by either using a switch boost converter which first produces high voltage direct current and then changes into AC using a line frequency transformer to create an output voltage. The output voltage can however be regulated to equal the gridline voltage.

  Note that the runtime of any inverter depends on the DC source power or the power being drawn from the inverter itself as it runs.

How Does an Inverter Work?

Most of the electric and electronic gadgets in our homes are made to run with AC energy. So, if you plan to power up your electronic gadgets with power from a top rated inverter generator such as the Champion or Honda models, or from a simple car battery or other fuel cells, you will need a device to convert the DC energy produced by such devices into alternating current (AC). And that device that converts DC into AC is called an inverter.

Most of the inverters found in retail stores use electromagnetic switches that run at extremely high speeds, flickering on and off as the action moves about in a back and forth action. The power produced in such a way is known as square wave output. However, electronic inverters produce smoothly alternating AC output from a DC input. While electric gadgets don’t care much about the waves used to convert power into them, electronic devices do, which prompted the invention of two distinct types of inverters, a pure sine wave inverter and a modified inverter.

The pure sine inverter uses donut shaped transformers and circuits to convert direct energy into a smoothly varying AC energy, similar to power supplied by normal power outlets. Most top rated inverter generators use these kinds of inverters. The kind of current they produce can power electronic gadgets such as TVs, laptops, video games as well as woofers. A modified inverter on the other hand uses rather simpler electronics to produce not so smooth alternating current. They are therefore only suitable for producing current for hefty electric appliances, otherwise using them on normal home appliances could lead to overheating and potential damage to your gadgets.

Note that uninterruptible power source inverters are capable of storing power by themselves in an electrical form, which you can then use should the power source get depleted.. The inverters store the energy in high speed flywheels.

Inverter Generator VS Conventional Generator

When compared to conventional generators, inverter generators are a recent development, made entirely of high tech magnets and electronic circuitry. They basically output AC energy like all other types of generators do but do it in a 3 phase form. While outputting the AC current, they convert the current to DC form, and then invert it back to AC current while it is pure and smooth, in a pure sine wave. Inverter generators are incredibly smaller in size when compared to their counterparts. They also produce relatively good amounts of power, although conventional generators beat them in terms of fuel storage capabilities, obviously resulting in more power. Don’t get it wrong though, as inverter generators use modern technology to maximize their use of fuel and running time, thereby producing much more power in the long run. They also run at varying speeds, thereby increasing their efficiency.

Conventional generators on the other hand run at a constant speed, but they lack features such as sound dampening technology, quiet engines or mufflers. They also come in varying watts, ranging from 500w to 50,000w with the higher watt generators producing much more energy to run big industries and companies.

Conclusion

Since the late 1800s when inverters were discovered, their functions and applications have multiplied rapidly. They are now found in generators, the machines that help convert DC stored energy into a form that can power up a laptop, a freezer, TV or any other electronic gadget. And while there are efforts to come up with a conclusive list of portable inverter generator comparisons, we believe that the six types of generators described above are simply the best by any standards. Finally, the future for inverter generators looks bright, with engineers and leading manufacturers gearing up to invent super powerful generators that are small in size but consume very minimal amounts of fuel.
