An inverter is a device that converts DC (direct current) voltage into AC (alternating current) voltage. It is used to convert the stored energy in batteries, which is in the form of DC, into AC supply. This allows us to utilize the stored energy to power appliances that require AC supply.
Inverter is basically a simple electrical device that converts DC voltage into AC voltage. There are many applications of inverters, like the use of inverters in UPS and in variable frequency drivers to control the speed of induction motors. But in this tutorial, I will tell you about the use of inverters in UPS.
There are different types of inverters available in the market, each with its own characteristics and capabilities:
- Iron Core Base Inverters: These inverters are generally cheaper in price but have lower efficiency compared to other types. They are commonly used for basic applications.
- Ferrite Core Base Inverters: These inverters have higher efficiency and are more expensive compared to iron core base inverters. They are suitable for applications where higher efficiency and performance are required.
In terms of the output voltage shape, there are three main types of inverters:
- Square Wave Inverter: This type of inverter produces output voltage in a square wave form. Square wave inverters are the least efficient in terms of power consumption and can produce high harmonics, which can impact the performance and lifespan of devices.
- Modified Sine Wave Inverter: Modified sine wave inverters produce an output voltage that is a stepped approximation of a sine wave. They are more efficient than square wave inverters but still have some harmonics. They are commonly used in applications where cost is a factor.
- Pure Sine Wave Inverter: Pure sine wave inverters produce a smooth and high-quality sine wave output, similar to the waveform of the grid power supply. They have higher efficiency, reduce harmonics, and provide the cleanest power output. Pure sine wave inverters are suitable for sensitive electronics and devices that require high-quality power.
It’s important to consider the efficiency, price, and output voltage shape when choosing an inverter for your specific needs. Different applications may require different types of inverters to ensure optimal performance and reliability.
Why and where is an inverter used?
We use batteries to store electrical energy to use stored electrical energy in case of an outage of the main electrical supply. But the problem is, batteries store energy in the form of DC. The appliances we mostly use at home or in the industry require AC supply. To solve this problem, we use an inverter. It is used to convert battery DC voltage to AC supply so that we can utilize the stored energy. Another important thing is the type of inverter you are using and how efficiently it converts the DC into AC and the shape of the output voltage. I will discuss all these things in my upcoming tutorials about inverters.
The output of the battery is 12V DC and it depends on your battery whether you are using batteries in series or parallel. I am considering a single battery whose output voltage is 12 volts DC and the required AC voltage for appliances is 220V AC and 50 Hz. The basic purpose of the inverter is to convert 12V DC into 220V AC, which has a frequency of 50 Hz.
Ferrite core and iron core inverters are different types of invertFerriteFerrite core and iron core inverters are two types of inverters that differ in terms of their core material. Here are the main differences between them:
- Efficiency: Ferrite core inverters generally have higher efficiency compared to iron core inverters. This means they can convert DC voltage into AC voltage more effectively, resulting in less power loss.
- Cost: Ferrite core inverters are generally more expensive than iron core inverters. This is because ferrite materials are more advanced and have better magnetic properties, which contribute to their higher efficiency.
- Performance: Ferrite core inverters offer better performance in terms of higher power handling capacity and lower core losses. This makes them suitable for applications where higher efficiency and performance are required.
- Size and Weight: Ferrite core inverters are usually smaller and lighter compared to iron core inverters. This is due to the characteristics of the ferrite material, which allows for more compact designs.
- Applications: Iron core inverters are commonly used for basic applications where cost is a significant factor. Ferrite core inverters, on the other hand, are suitable for applications that require higher efficiency, such as renewable energy systems and high-performance electronics.
It’s important to consider these differences when choosing between the ferrite core and iron core inverters, as they can impact the overall performance, cost, and suitability for specific applications.
