The 24V DC power adapter manufacturer tells you that the function of the power adapter is a transformer and a rectifier. Therefore, it is certain that the power adapter is a transformer-cum-rectifier.

The 24V DC power adapter manufacturer tells you that the power converter (both AC to DC) converts alternating current to direct current, and then passes through the computer. It cannot protect the computer, but the computer has a memory (also called a charger) that stores power. So you can protect your computer in the event of a power outage. 24V DC power adapter manufacturers tell you that both switching power supplies and adapters are switching power supplies, which are composed of high-frequency switching tubes and their control circuits. The adapter power supply is a regulated switching power supply. The switching power supply charger has a floating charging function. The voltage increases with the decrease of the current. In the end, there is only voltage but no current.
24V DC power adapter manufacturers tell you that it is widely used in consumer electronic products, and most of the output power provided is within 100 watts, and the market demand is growing rapidly. Such as electric bicycle battery chargers, small LCD TVs, notebook computers, printers, DVD players and set-top boxes, etc. have applications. 24V DC power adapter manufacturers tell you that most of the early power adapters used linear transformers. With the requirements of high efficiency and wide input voltage range for power adapters in consumer electronic products, and the increase of copper, iron and labor costs, such power adapters Most of the original linear transformers inside are gradually replaced by switching power supplies.
