Before enumerating the advantages and disadvantages between AC and DC gears, we have to make a brief definition of both systems, when we speak of dc we are referring to the electrical charges that flow over a conductor of the shape-invariant, i.e. which do not change their intensity over time. Alternating current behaves differently, which is crucial when you buy gears online, unlike the continuous or direct this if varies its intensity as time goes by, this is given by the electrical loads changing their direction of movement in the driver periodically.
How to choose the best gear?
The transport of alternating current is more economical than continuous, the cost of reducing or raising the voltages for alternating current are lower than in dc. It is for this reason that households use alternating current to transport the energy from the hydroelectric power stations to our homes it is necessary to raise the voltage at various points of the route and then reduce it to get to residential areas (this is done to mitigate the loss arising in the transport of energy). The range of voltages that are obtained by the use of the transformer.
The machines that use ac are simple, robust and do not require much maintenance and repair during its use. The alternating current can be quickly converted into direct current with the aid of rectifiers. When the alternating current is supplied at a voltage high in a long-distance transmission, the losses of the line are minor if we compare them to a transmission of direct current.
DC gears and their advantages
On the other hand, the maximum value of the alternating current is very high and can sometimes be dangerous, so it requires a higher insulation. While the continuous current gives an electric shock that repels the human body, the alternating current attracts the person that touches it directly. It can use voltages lower to transmit electricity through the cables, since they are less resistant to the continuous current. One of the main advantages is that the dc current can be stored in batteries, this is undoubtedly a large advantages over the alternating current. The dc is much safer than alternating current.
There are fans of high quality with an AC motor as a DC. Fans that are extremely quiet, does not wobble and create a good movement of air. And even though the AC motor consumes a bit more power than the DC one, both types of fans used an amount of energy much lower than that used by most appliances, especially air conditioners. Without turning on your air conditioning and using your fan, is like really save you money. So once you have decided on your style, budget, and functions needed, feel safe opting for a AC or a DC.
