What is Inverter Generator:How do it work?

If you want to power delicate appliances, then, inverter generators are the best option for you to ensure that your appliances are not damaged by power surges whenever there's a power outage. Although, there are a variety of inverter generators on the market, each with different features and benefits. And when choosing an inverter generator, it is important to consider your specific needs and choose a model that will meet those needs. Anyway, maybe you are just hearing about inverter generators and don't know what they are and how they work. In this article, l will explain in detail all you need to know about these types of generators and how they work.

What is an inverter Generator?

An inverter generator is a type of generator that produces alternating current power also known as AC-the power is then converted to direct current (DC) power by an inverter.

Inverter generators are more expensive and productive than traditional generators and produce less noise. Also, they are lighter in weight and are more compact, making them ideal for camping, RVing and much more-offering a stable power output.

How Does inverter Generator Work?

Inverter generators work by converting Ac power into Dc power, which is then inverted back into Ac power as explained above.

This process is more efficient than traditional generators, and it produces cleaner power that is lesslikely to damage sensitive electronic equipment such as television, laptops and more.

Moreover, inverter generators are a great choice for people who need a reliable, portable power source.

Why Do You Need An inverter Generator?

The main difference between an inverter generator and a standard traditional generator is that aninverter generator produces cleaner power. This is because the power produced by an invertergeneratoris more stable and has fewer voltage fluctuations.

Inverter generators are ideal for sensitive electronic equipment, such as TVs, computers, and microwaves. They are also quieter than standard traditional generators, making them perfect for camping and RVing.

So, if you need a generator for your home or recreational activities, an inverter generator is a great option to opt for.

How did the inverter generator develop? 

Before the inverter generator was successfully developed, the speed regulation performance of the Variable-frequency Drive used could not reach the required frequency conversion speed. After the breakthrough in the research on pulse width modulation variable voltage frequency conversion (PWM-VVVF) speed regulation, various optimization algorithms It is also easily realized due to the improvement of microprocessor technology.

Later, the Japanese successfully developed the earliest inverter machine after purchasing British patents, and the high-end products developed by the United States and the United States, relying on their advantages in electronic component production technology, quickly seized the market at that time. Now my country has a place in the high-end market of the 21st century, and a number of well-known domestic inverters have emerged.

Benefits of Using inverter Generator

The main benefit of an inverter generator is that it can produce clean power that is safe for sensitive electronics. inverter generators are also usually smaller and more lightweight than traditional generators,making them more portable.

Inverter generators are typically more expensive than their traditional counterparts, but they offerseveral advantages that make them worth the additional cost.

Also, inverter generators are much quieter than traditional generators. This makes them ideal foruse in camp grounds and other areas where noise pollution is a concern.

Additionally, inverter generators are more fuel-efficient than traditional generators, making them agood choice for extended use.

What are the disadvantages of inverter generators?

The main performance is still in his motor. Although permanent magnet motors bring performance advantages at low speeds, they are also a technical "Achilles heel". For example, as the speed of a permanent magnet motor increases, the back EMF approaches the inverter supply voltage, making it impossible to control the winding current. This defines the base speed of a universal permanent magnet motor and in surface magnet designs usually represents the maximum possible speed for a given supply voltage.

At speeds greater than base speed, IPM uses active field weakening, where the stator current is manipulated to deliberately suppress the magnetic flux. The speed range that can be reliably implemented is limited to around 4:1. As before, this limit can be achieved by reducing the number of winding turns and accepting greater costs and power losses in the inverter. The need for field weakening is speed dependent and will result in associated losses regardless of torque. This reduces efficiency at high speeds, especially at light loads.

Other disadvantages include the fact that it is difficult to manage under fault conditions due to its inherent back EMF. Even if the frequency converter is disconnected, current will continue to flow through the faulty winding as long as the motor is spinning, causing cogging torque and overheating, both of which are dangerous. For example, field weakening at high speeds can lead to uncontrolled generation due to inverter shutdown, and the inverter's DC bus voltage can rise to dangerous levels. In addition to those permanent magnet motors equipped with samarium cobalt magnets, operating temperature is another important constraint. And high motor currents caused by inverter failure can cause demagnetization. Maximum speed is limited by the holding force of the mechanical magnet. If the permanent magnet motor is damaged, repairs generally require returning to the factory because it is difficult to safely extract and process the rotor. Finally, the issue of end-of-life recycling is also a headache, but the current high value of rare earth materials may make such materials more economically viable.

Conclusion

Inverter generators are a great investment for people who need a portable power source. They are easy to use and maintain, and they provide a reliable source of power when you need them.
