The main advantages of AC power supply
Time：2023-12-08
Ac power supply, with its unique advantages, plays an indispensable role in modern electronic equipment. This form of power supply, whose voltage and current waveform changes periodically in time, is fundamentally different from DC power supply. This article will explore the main advantages of power AC loads in detail.

Efficient energy conversion
Ac power allows efficient energy conversion. In many electronic devices, such as household appliances and industrial equipment, alternating current is converted to direct current to drive the load. Since the waveform of an AC power supply has peak and valley values in each cycle, higher energy conversion efficiency can be achieved throughout the waveform cycle.
Easy to transmit over long distances
Another significant advantage of AC power is its relatively small loss over long distances. Because the voltage and current of alternating current decay naturally during transmission, it requires less power loss over long distances than direct current.
High compatibility
Ac power supplies excel in terms of compatibility. Different countries and regions may have different power supply standards, such as 110V/220V, 50Hz/60Hz, etc. However, regardless of the standard, alternating current can be converted by the appropriate transformer, making electronics more compatible across the globe.
Reduce electromagnetic interference
The use of AC power supplies helps to reduce electromagnetic interference (EMI). Because the waveform of alternating current changes direction during each cycle, the electromagnetic field it produces is relatively uniform in space, thus reducing electromagnetic interference. This characteristic makes AC power sources more advantageous in many high-precision electronic devices.
Cost effective
While AC power supplies may require additional conversion equipment (such as power adapters or transformers) for initial use, they are generally cheaper in the long run due to their efficient energy conversion and lower transmission losses. In addition, due to its wide compatibility, design and production costs are also reduced.
In summary, AC power supplies have the advantages of efficient energy conversion, easy long-distance transmission, high compatibility, reduced electromagnetic interference, and high cost effectiveness. These advantages make AC power supply widely used in various electronic devices and systems. However, it is important to note that each power supply type has its specific application scenarios and limitations, and which power supply to choose should be determined according to the needs of the specific device and system.
