This makes it possible to create pseudo sine waves of various frequencies and control the rotation speed of the motor simply by specifying desired parameters.

Inverter circuits and devices are used in various electrical products such as household air conditioners, refrigerators, IH induction heating cookers, fluorescent lights, computer power supplies including UPS , industrial fans, pumps, elevators, and cranes.

They are widely used and have become an integral part of our lives. As mentioned in the beginning, inverter circuits and devices are used in household air conditioners, refrigerators, industrial pumps, elevators, etc.

There are no built-in motors in IH cookers or fluorescent lamps, but changing the frequency with the inverter circuit lets you finely adjust heat and brightness. For example, an IH cooker uses high frequency in its coil that heats the pot, utilizing the inverter circuit. Fluorescent lamps also use alternating current in high frequency to increase the lighting speed in order to maintain brightness and suppress flickering with low power consumption.

Last but not least, the inverter circuit also works in computer power supply units. Be prepared for sticker shock -- a perfect sine inverter can cost almost 10 times as much as the same wattage inverter with a modified sine output. Modified sine means that the current is run through some filtering, so it isn't a square wave, but it isn't totally smooth either. You won't be powering a washing machine or clothes dryer with an inverter, so you'd better get out the washboard and the clothesline.

Most U. Inverters are very easy to install. Most of them are "plug and play" devices, especially smaller, low-wattage inverters. These inverters have a cable with a plug that fits into the cigarette lighter on your car or truck. They're meant to be portable, so there's no other mounting to be done. Below watts, the cigarette lighter connection is still a possibility, but wattages above that require direct connection to the battery.

The inverter's input cables have clips that can be attached to the terminals of the battery, similar to a set of jumper cables. If the installation is to be permanent, the cables can be bolted to the terminals. The inverter itself can be mounted anywhere, although it should be in a place with good air flow. Inverters generate a fair amount of heat, and they use cooling fans and heat dissipation fins to prevent overheating.

Larger, heavier inverters have mounting holes in their chassis so they can be bolted to any surface. Obviously, with a permanent installation, you'll probably want to bolt your converter in place, but this isn't absolutely necessary. It's possible to simply place the inverter in a secure, stable position, clip the leads to the battery and plug in. Just what does an inverter look like, anyway? Well, the smallest inverters can fit in your pocket, while higher-wattage models are roughly the size and weight of a large dictionary.

As a general rule: The higher the wattage, the larger and heavier the inverter. At the top of the inverter wattage scale, some inverters can be more than two feet long and weigh over 30 pounds. Modern inverters have some built in safety features that make them even easier to use. Some models sound an alarm when the battery's voltage gets too low. This is more of a convenience, but depending on what sort of equipment you're powering, it could also be a valuable safety feature.

Inverters typically have automatic shut-off capabilities, too. If the unit detects a current overload or an overheating situation, it will shut down to lessen or prevent the chance of a fire. Inverters can also shut off in the event of a short circuit, such as a piece of metal falling into the chassis or the inverter getting wet. Short circuit shut-off is an effective way to prevent electrocution.

Inverters are just one example of a class of devices called power electronics that regulate the flow of electrical power. Fundamentally, an inverter accomplishes the DC-to-AC conversion by switching the direction of a DC input back and forth very rapidly. As a result, a DC input becomes an AC output.

In addition, filters and other electronics can be used to produce a voltage that varies as a clean, repeating sine wave that can be injected into the power grid. The first inverters were created in the 19th century and were mechanical. A spinning motor, for example, would be used to continually change whether the DC source was connected forward or backward. Today we make electrical switches out of transistors, solid-state devices with no moving parts. Transistors are made of semiconductor materials like silicon or gallium arsenide.

They control the flow of electricity in response to outside electrical signals. If you have a household solar system, your inverter probably performs several functions. In addition to converting your solar energy into AC power, it can monitor the system and provide a portal for communication with computer networks. Solar-plus—battery storage systems rely on advanced inverters to operate without any support from the grid in case of outages, if they are designed to do so.

Historically, electrical power has been predominantly generated by burning a fuel and creating steam, which then spins a turbine generator, which creates electricity. The motion of these generators produces AC power as the device rotates, which also sets the frequency, or the number of times the sine wave repeats.
