Most of the well-known devices that we use everyday are converting Alternating Current (AC) to Direct Current (DC) and using an equipment with Direct Current (DC) to Direct Current (DC) is also an option as well. First, let us understand the difference between the two.
HOW DOES AC-DC (Alternating Current-Direct Current) WORK?
In most buildings you see in the city an AC-DC power supply is used since there’s a lot of devices that are needed to use electrical power and AC-DC power Supply is best to supply these huge demands.
ACDC converters need AC powers first from wall outlets and then convert them into unregulated Direct Current with the use of transformers that change the voltage to be compatible with what the connected device needs. This is perfect for office buildings that have different types of equipment.
The green line in the image above represents the AC-DC Power Supply.
Now we understood how AC-DC Power Supply works, let’s find out
HOW DOES DC-DC (Direct Current-Direct Current) WORK
Unlike the equipment you used in offices, DC-DC Power Supply is commonly used in Battery-Operated Devices. One perfect example is your Cell Phone.
A DC-DC power supply converts direct current coming from the power source (a battery) from one voltage level to another depending on the point-in-time needs of the device being supplied. In a Cellular Phone you’ll see several sub-circuits that need various voltage level requirements that they need for the power supply (battery).
Both AC-DC and DC-DC Power Supplies need converters and transformers. Most common peripherals that are used were Power Adapters and these Power Adapters are needed for the smooth operation of devices and Equipment.
Switching Power Adapters are very helpful. Not only do they help with the optimization of the equipment’s performance, but they are also specially designed to meet your specific technical and performance requirements.
