What is AC-DC power supply?
was a time when some places were supplied with direct current (DC) and others used the power of AC current (AC). If the AC-DC description has a power supply, this means that the device can work on an alternating current or direct current. AC conversion to DC is the main function of AC-DC power supply. Buildings and houses are supplied with an alternating power supply, which is supplied on a live wire and heads back to the return wire to complete the circuit. The direct current is when electricity flows in the same direction and is always positive or negative. Many devices run on DC power and cannot run on alternating performance. The device traditionally converts one form of electricity to another. Power sources can be found on many things, such as TV files, computers, video game consoles and even idom phones. Napissance sources are commonly found on devices that use a charged battery such as mobile phones and other pocket devices.
The power of the AC, which flows into the houses, is too powerful for most DC appliances. This means that the voltage of electricity must be reduced. In principle, alternating power enters the AC-DC power and immediately passes through the coil and creates a magnetic field. The magnetic field creates an electric current on the second coil, which is next to the first coil. This second coil contains less wire speed to create a lower voltage of alternating electricity.
AC-DC power supply contains a rectifier that uses a diode to separate positive and negative electricity. When electricity is negative, the diode allows it to flow through the negative wire, but blocks the positive wire. As soon as electricity turns into a positive, the diode switches and allows the choice of polishing a political bank. There are different types of rectifiers, but they all do the same basic thing.
Some power sources use the filter capacitor and select the appropriate regulator to generate a clean DC signal. Capacitors are used forBlocking the AC power supply and allow you to pass by DC power. This makes the power output smoother when used on a device that uses radio frequencies.
In the past, all TVs and radios used vacuum tubes. It was a device that would control the movement of electrons in a low -pressure space to modify or create an electrical signal. AC-DC power has allowed these devices to be controlled without the use of a transformer. This was a problem because the transformers were expensive and could not be used with DC Power.
