![]() One of the main advantages of DC electricity is that it is easier to store than AC. Let’s have a closer look at the positives and negatives of both electric currents. ![]() Westinghouse and Tesla were able to demonstrate the superiority of AC electricity compared to the earlier established DC electricity from Thomas Edison. Now that you know what AC and DC is, let’s compare both of them and see what is best. AS an international standard, AC is used in all home appliances and electric machines. On a graph, it could be represented by a wave.ĪC electricity is produced by an alternator in nuclear, hydroelectric, coal and gas power plants for example. Meaning to say the current changes direction 60 times per second. As it is named, in AC, the current flows alternatively in both directions at a standard frequency of 60Hz. What is AC?ĪC stands for Alternating Current. On a graph, it could be represented by a continuous straight line.ĭC electricity can be produced by solar panels for example, and stored in batteries which also deliver DC electricity. The electrons are flowing from the negative pole to the positive. As it is named, in DC, the current flows in one direction. To understand why AC was adopted as an international standard let’s us first explain what AC and DC are. However, DC is not dead and with the development of renewable energies such as solar power which generates DC and DC alone, there is a renewed interest in direct current electricity. Well, I guess you already know the end of the story, Westinghouse and Tesla beat Thomas Edison in the fight for electricity standards, as AC is now world recognized and used for electricity generation. A recent movie, paints a good picture of the harsh fight between the two men, escalating up to the first human execution in an electric chair powered by AC. Two years later, he met George Westinghouse, a rich industrialist, who bought many of his patents, and began to develop AC power stations.Īnd this marked the start of an epic battle between Westinghouse/Tesla and Edison for the development of electricity standards. However, he was convinced that the future of electricity was with Alternating Current (AC). Ironically, Tesla arrived in the US in 1884 and started to work for Edison on DC machines. The first electrical systems were established by Edison as direct current (DC) power stations that began to serve their first 59 customers in New York in September 1882. George Westinghouse, backed by Tesla, was a passionate advocate of AC electricity, whereas Edison strongly pushed for DC to be adopted as the international standard. Tesla, Edison and Westinghouse were engaged in perhaps the most dynamic technical battle of the modern era. ![]() A time when electrical science showed tremendous development thanks to great scientists such as Alexander Graham Bell, Werner von Siemens, Heinrich Hertz, George Westinghouse, Nikola Tesla and Thomas Edison. Let’s go back in time, to the end of the 19 th century. Here's a brief history of AC and DC: The Long Lasting War ![]() ![]() Now, let’s see why we have two types of electric currents. An electric current is a flow of charged particles (the electrons) in a conductor, for example in an electric wire. However, much before the band became famous the term AC and DC was well known.ĪC and DC are electric currents. The first thing that likely pops to mind are these guys right? Finally, we will describe what appliances you could run without converting DC to AC. Secondly, we will look how to convert DC into AC via an inverter. In our article, you will find everything you need to know about DC to AC converters.įirst, we will explain what DC and AC are, then we will move along to answer the question: Is AC better than DC? Therefore, there is a need for a efficient DC to AC power converters both for domestic and industrial use. On the one hand, these systems named above mostly produce, store and use DC electricity, on the other hand, the international standard for electrical devices and home appliances is AC electricity. DC to AC power converter is essential if you want to use electricity from: Lead-Acid Battery Charging Cable - 12V/24VĭC To AC Converter (Understanding How Power Converters Work)Ĭonverting DC (direct current) to AC (alternating current) has played a major role in the transition toward renewable energy.
