When looking for electrical devices, it is important to understand the difference between power converter vs inverter. Both of these devices convert energy from one form to another, but they do so in different ways. 

Not only are they found in different places on the market, but they also have different applications. One of the major differences between power converters and inverters is the type of energy that they convert. In short power converters transform AC current into DC current, while inverters change DC current into AC current. 

You can find these devices used in almost all applications such as solar power, electronic equipment, and even automobiles. Trying to use a device without them can be dangerous, and in some cases, could damage your equipment and so knowing the correct device and type for your needs is essential.

When choosing between a power converter and an inverter, it is important to understand the difference in their applications. Power converters are typically used in devices that run on batteries or DC current. These devices include solar panels, laptops, and even automobiles. Inverters, on the other hand, are used in devices that run on AC current. This includes most appliances in your home such as your refrigerator, stove, or air conditioner.

What is a Power Converter?

Power converters are used to change Alternating Current (AC) into Direct Current (DC). This is important because many devices, particularly electronic ones, run on DC power. For example, your laptop runs on a battery that stores DC power. By using a power converter, you can change the AC from the wall outlet into DC so that your device can run properly.

What is an Inverter?

Inverters are used to change Direct Current (DC) into Alternating Current (AC). This is important because most devices, particularly household appliances, run on AC power. For example, your refrigerator runs on AC power that comes directly from the wall outlet. By using an inverter, you can change the DC from a battery or solar panel into AC so that your appliance or machine can run properly.

Which one do I need?

Now that you understand the difference between power converters and inverters, it is important to also know the different types of each device. Not every power converter or inverter is the same, and so knowing which one you need is essential.

There are three main types of power converters: Analog-to-digital converter (ADC), digital-to-analog converter (DAC) and digital-to-digital converter (DDC),

There are also three main types of inverters: Square wave inverter, quasi wave or modified square wave inverters and true/Pure Sine wave inverters.

Not to worry though, in the next section we will go over each type of converter and inverter in more detail so that you can make an informed decision on which one you need.

Different Types of Power Converter

So, we know that power converters convert AC current into DC current. But what are the different types of power converters? Well, we know that power converters come in three different types: Analog-to-digital converter (ADC), digital-to-analog converter (DAC) and digital-to-digital converter (DDC). But what do these terms mean?

1. Analog-to-Digital Converter (ADC)

An ADC is a power converter that takes an input signal in the form of an analog voltage and converts it into a sequence of digital values. This type of converter is important because many electronic devices, such as laptops and smartphones, only understand digital signals. By converting the analog signal into a digital value, the ADC allows these devices to understand the signal and function properly. These types of converters are also known as rectifiers.

2. Digital-to-Analog Converter (DAC)

A DAC is a power converter that takes a sequence of digital values and converts it into an output signal in the form of an analog voltage. This type of converter is important because many electronic devices, such as music players and televisions, only understand analog signals. By converting the digital signal into an analog voltage, the DAC allows these devices to understand the signal and communicate with the outside world. They are also known as samplers.

3. Digital-to-Digital Converter (DDC)

A DDC is a power converter that takes an input signal in the form of a digital voltage and converts it into another sequence of digital values. This type of converter is important because it allows two devices, such as a computer and monitor, to communicate with each other. By converting the digital signal from one device into another, the DDC allows these devices to share information and communicate with each other. Also commonly known as a translator.

Different Types of Power Inverter

Now that we know what a power inverter is, let’s take a look at the different types of inverters. We can break inverters down into three main categories: Square wave inverters, quasi wave or modified square wave inverters and true/Pure Sine wave inverters. Let’s take a look at what each of these types mean.

1. Square Wave Inverter

A square wave inverter is the most basic type of inverter. This type of inverter takes a DC input and transforms it into a square wave AC output. Its most common usage can be found in small appliances and tools. As the name suggests, this type of inverter produces a square wave output, which can be harsh on electronic devices. Because of this, it is not recommended to use a square wave inverter with devices that are not specifically designed to work with them.

2. Quasi wave or Modified Square Wave Inverters

A quasi wave or modified square wave inverter is an improved version of the square wave inverter. This type of inverter takes a DC input and transforms it into a quasi or modified square wave AC output. This type of inverter is more forgiving on electronic devices than the square wave inverter and is more commonly used in larger appliances and tools.

3. True/Pure Sine wave inverters

A true/pure sine wave inverter is the most advanced type of inverter. This type of inverter takes a DC input and transforms it into a true or pure sine wave AC output. This type of inverter is the most compatible with electronic devices, as it produces a smooth, clean signal that is close to what you would find in a standard AC outlet. Because of this, it is the best type of inverter to use with devices that are sensitive to power fluctuations.

Main Differences Between Converter and Inverter

Let’s take a look at the major differences between a power converter and a power inverter.

Power Converters

  • Convert an analog signal into a digital value
  • Common in devices that only understand digital signals
  • It connects the power source to the supply output
  • It is used in a variety of appliances including charging devices and batteries

Power Inverters

  • Convert a DC input into an AC output
  • Can be either square wave, quasi wave or pure sine wave
  • It obtains energy from solar panels and batteries, then in turn powers the appliances
  • Most commonly used in larger appliances and tools

Conclusion 

There you have it, a breakdown of the different types of power converters and inverters. Hopefully this article has helped you better understand the differences between these two types of devices. When deciding which type of converter or inverter is right for you, it is important to consider the needs of the appliance or device you are trying to power.

For smaller appliances and devices, a square wave inverter may be sufficient. However, for larger appliances and tools that are more sensitive to power fluctuations, a true/pure sine wave inverter is recommended. Thanks for reading!
