DC to AC Converter

Learn more about DC to AC Converter, its characteristics, and main benefits.

The electrical circuits that transform direct current (DC) input into alternating current (AC) output are known as DC-to-AC Converters or Inverters. DC-to-AC Converters are considered to be one of the most important elements in power electronics. DC-to-AC Converters or Inverters are used in power electronic applications where the power input is pure 12V, 24V, and 48V DC voltage and requires power conversion for an AC output with a certain frequency. DC-to-AC Converters are essential because of how they are used in real-life applications.

 AC and DC are electric currents. An electric current is a flow of charged particles in a conductor.


  • DC stands for Direct Current. Most people learn about Direct Current in their introduction to electricity. In DC, the current flows in one direction. The electrons are flowing from the negative pole to the positive. DC electricity can be produced by solar panels and stored in batteries which also deliver DC electricity. The best way to visualize it is to think of a battery. If you connect the battery terminals with conducting wire, electrons flow from the negative terminal to the positive one. 
  • AC stands for Alternating Current. In AC, the current flows alternatively in both directions at a standard frequency of 60Hz with the current changing direction 60 times per second. AC current doesn't move through the wire in the same way DC current does, instead of flowing in a single direction, AC current reverses direction many times per second due to the way it's generated. AC electricity flows into our homes or businesses from the electric power grid and is constantly changing its flow between positive and negative terminals.


Characteristic of DC Power Supply: 

Direct current in which electricity always flows in a constant direction has its following advantages and disadvantages


      • Can store electricity
      • No advance or delay in the circuit
      • No reactive power is generated


      • Difficult to convert voltage
      • Current interruption is difficult
      • Strong electrolytic effect

Characteristic of AC Power Supply

AC with its cyclic positive and negative voltage has the following advantages and disadvantages.


      • Easy to transform
      • Easy to shut down while power is flowing
      • Less power loss due to high-voltage transmission
      • No need to worry about positive and negative voltage


      • Requires a higher voltage than the target voltage
      • Not suitable for ultra-long-distance transmission
      • Affected by coils and capacitors


DC-to-AC Converters or Inverters are used in numerous applications such as traction drives, PV systems, variable speed drives, and battery storage systems. The circuits are mainly used for driving low-power AC motors and in a solar power system. DC-to-AC Converters are also used to charge vehicle batteries and DC transmission lines for transmitting power to loads.  DC to AC conversion is important because your appliances require a 120V sine wave. AC has been the norm for such a long time which is why most devices are designed like this. Nowadays, some appliances use both DC and AC. Generally, though, appliances require AC power. This is why you must have the correct DC-to-AC converter at home. It’ll allow you to power all your appliances with the correct voltage and AC wave.

DC to AC conversion is also necessary because most power sources, such as generators and batteries, produce DC power, while most appliances and devices use AC power. Additionally, the transmission and distribution of electrical power over long distances are more efficient with AC power. DC to AC conversion allows for the use of this more efficient transmission method while still powering devices that require AC power.

The main benefits of using a DC-to-AC converter include:


DC to AC converters allows the use of DC power sources, such as batteries or solar panels, to power AC devices and appliances.


DC power sources are often more portable than AC power sources, so a DC-to-AC converter allows for the use of portable power sources in places where AC power is not available.


DC to AC converters can be more efficient than traditional generators in certain applications.


DC power is less likely to cause electrocution or electrical fires than AC power, and a DC to AC converter can be used to convert DC power to AC power safely.


DC-to-AC converters can be less expensive than traditional generators in certain applications.

Reduced harmonic distortion

In certain applications, especially in sensitive electronic equipment, DC-AC inverters can be used to reduce harmonic distortion.

A DC-to-AC inverter is needed when there is a need to convert DC power to AC power. This can be done for a variety of reasons, including:

      • To power AC devices and appliances: Many electronic devices and appliances, such as lights, fans, and televisions, are designed to run on AC power. A DC to AC inverter can be used to power these devices from a DC power source, such as a battery or solar panel.
      • For portable power: DC power sources, such as batteries, are often more portable than AC power sources. A DC-to-AC inverter can be used to convert DC power to AC power and make it possible to power AC devices in places where AC power is not available.
      • For off-grid power systems: In off-grid power systems, such as solar panel systems, the power generated is in DC form and it's necessary to convert it to AC to be able to use it in the home appliances.
      • To improve power quality: DC-AC inverters can be used to improve power quality by correcting power factors and voltage regulation in some applications where that is needed.

The best inverters for converting DC to AC power will depend on the specific requirements of your application. In general, the following factors should be considered when selecting an inverter:

      • Power rating: The inverter must be rated for the power level required by the load.
      • Efficiency: Look for an inverter with a high-efficiency rating, as this will help to reduce power loss and save on energy costs.
      • Power quality: Look for an inverter with features such as low harmonic distortion and power factor correction, which can help to improve the quality of the output power.
      • Reliability: Choose an inverter with a good reputation for reliability and durability.
      • Price: Compare prices and features of different inverters to find the best value for your needs.

We are living in an energy transition from a fossil fuel-based to a zero-carbon economy. Electricity is playing a major role in this energy transformation. The global electricity demand is expected to get very strong and that’s why it is important to be wise in your spending decisions.
