Inverter technology is one representative of multiple modern renewable energy technologies. Great achievements have been made these years in inverter area. The advanced inverter technology has wide applications and extensive benefits. Knowing more about inverter technology is helpful to build an eco-friendly environment with low energy consumption and low noise.  

Identification of inverter technology

First of all, what is inverter? An inverter is a kind of
voltage converter which also includes rectifier. An inverter is designed to convert DC current to useable AC current for any AC appliances. This voltage converting process applied the technology of inverter.

Inverter technology is one of the latest renovation of electro compressor motor technologies. This technology was adopted in the air conditioning units as early as 1980s. Nowadays inverter technology is used more widely, ranging from home appliances like TV, emergency lights, electronic fans, cellphone chargers, radios, to automobile accessories like car refrigerator, air-conditioner and office equipment including laser printer, computer. 

Inverter technology actually applied the amplifier technology. For example, in air conditioners, the inverter technology is used to heating technology. The inverter unit has a variable-frequency drive that includes an adjustable electrical inverter which can control the speed of compressor motor. In that case, the compressor and output of cooling/heating are adjusted accordingly, so the air conditional would always work at a stable speed.

Functions of inverter technology
Inverter technology plays an important role in electronic field because of its multiple advanced functions.

1. Voltage conversion

An inverter converts DC power generated from other power resources to different voltage in order to supply enough power for a load or distributed grid.

2. Power transfer optimization
Inverters can optimize the transfer of power by Maximum Power Point Tracking. This optimization is supported by figuring out the ideal equivalent resistance of current, voltage, and the respective change rate.

3. Grid Synchronization
The inverter output is built in the form of wave. This AC waveform is synchronized with utility electrical distribution system.

4. Disconnection
Built-in multiple protection systems, an inverter can disconnected automatically from the power distribution system.

5. Storage interfacing
Inverters may enable batteries or other devices to store energy form distributed generator.

Benefits of inverter technology
There are many advantages to use inverter technology. That is why more and more people want to renew and use inverter technology in daily life and industry field.

Equipment with inverters can help reduce up to 50% energy costs, more energy-efficient than non-inverter devices.

More stable
When using inverters, there is no ON/OFF transition that non-inerter system has so that the temperature condition maintains more stable with less fluctuations. That is why inverter technology was applied easily in air conditioners.

Less noise
Equipment with inverters has lower noise when in operation, as the motor with inverters inside can regulate itself automatically, so the motor can work rarely with full energy.

Inverters can faster response to the variable heating and cooling loads reach the target temperature than non-inverters. That also brings more comforts for people.

Built-in protection systems, an inverter can effectively reduce the risk of electromagnetic interference with other equipment.

Inverters can compute the peak of current, voltage from compressor intelligently.

Trends of inverter technology
With rapid developing of technology, inverter technology is deemed to have a brighter and further future. The future trends will be embodied mainly in two facts.

Function expansion

As mentioned above, there are a lot of standard functions of inverters. Coming back the revolution of inverter technology, you may find that inverters are fist called DC to AC voltage converter, and later inverters were expanded in PV systems. At present, inverters are serve for a large areas including household, motors, communication, monitoring, energy storage, grid interaction, emergency, etc. More inverter functions will be explored and applied in the future. Inverter technology will contributed to build a smarter home, smarter office by controlling and regulating the load for energy distributing and shifting. On the other hand, inverter technology will also show its advantages in macro field to help build mini-power structure against traditional large single power source.

Smaller size

With the expanding of inverter functions, inverters will be used in a wider areas and portability will be one problem that people focused on in the future. Smaller inverters with compact appearance and light weight, will be more convenient for people to take out for traveling and other outdoor activities. In the future a cost-effective inverter will be a new electronics charging demand.

Inverter technology is a great progress in human development process. Multiple inverter functions and benefits will bring more convenience to industry and life, and build an eco-friendly environment.
