It is easy to operate. AC motors are cheaper and quieter than the DC motor. DC welders can be more versatile and flexible than AC welders. Then, depending on the instrument, the current is either used directly or, by the use of converters, in DC form as not only it is easier to produce, it is also easier to convert. We all are aware of the basic definition of Direct Current (DC) and Alternating Current (AC). There are many advantages and disadvantages of AC system over DC system. This was an easy choice because batteries are also DC. Those coming from solar power and other renewable sources still make up very small portion of the generation. The majority of DC fans are low-voltage fans. Choppers are inadequate due to unsteady voltage and current supply. In spiteof initial wide spread of dc power they havecertainlimitations that dc power should be generated and delivered to short distances, for long distance transmission I2R losses and voltage drops in the lines were not acceptable for generation of the dc power.

For the high voltage DC (HVDC) transmission, only two conductors (positive and negative) are used. As discussed before, this allows for improvement of energy efficiency in electrical transmission with powerlines. It requires more conductor material (copper or aluminum). AC transmission lines require more conductor material than the DC transmission lines as three wire are required for AC transmission. AC devices are robust, simple, useful, and do not need much attention for their maintenance and repairs during their operation. Their other advantage is that they are much more widespread due to their lower price. The amount of conductor material required is more as compared to dc transmission lines. Edison developed direct current -- current that runs continually in a single direction, like in a battery or a fuel cell. Therefore, the AC transmission permits to transmit the electric power at high voltages and to distribute it at lower voltages. The ac can be easily converted into dc. What are the advantages and disadvantages of using AC vs DC power lines (electric lines that connect power plants and transformers to buildings and consumers)? DC drives are less complex with a single power conversion from AC to DC. for example AC microgrid has capable to integrate with conventional utility grid and can support AC equipment like Induction Motors.

Alternating current is the optional current generally as it has several clear advantages in comparison with direct type. It is because the skin effect takes place in AC transmission line. Electronically commutated (EC) fans use EC motors, which are just brushless DC motors that include an external circuit board and the ability to run on both AC and DC power. An AC transmission line has line capacitance. AC can be easily converted into DC using the rectifier (an electrical device that converts AC to DC). Disadvantages of High Voltage AC Transmission System 1. DC disadvantages: 88-92% efficiency range for most motors So, I think the bloggers explained its advantages very well. This is the best reason to prefer alternating current over direct current for the transmitting process of electricity, as it is much cheaper to modify the voltage of the alternating current. The next equation: if the voltage is improved, the current is reduced relative to transmit the same energy. Allow Necessary Cookies & Continue AC motors produce alternating current, while the DC motor produces direct current. Each transmission system has its own advantages and disadvantages. Torque control available from Zero Speed without an encoder Easy to repair and recondition Typically outperforms AC motors for stall operations. Of course, a reduction of the resistance would decrease the energy lost as well, but the current has a larger influence on the energy waste because of its amount being squared. AC and DC can coexist and each serve a purpose. Nowadays, electric power is almost generated, transmitted and distributed in the form of AC supply. Due to the above reasons ac power out rule the dc power for generation,transmissionand distribution. The magnitude of the current can be reduced by using an inductance or a conductor without any appreciable loss of energy. Advantages of AC Motors vs. DC Motors.
