Power adapter and switching power supply characteristics and differences
Power adapter and switching power supply is different, their specifications, shape size, precision density, performance and other parameters are different, its application is also different. Power adapter is mainly used for small appliances, electronics, and switching power supply is the control of the entire switch conversion current equipment for all electronic equipment. Xiaobian to focus on the following to explain the characteristics of power adapter and switching power supply and the difference.
First, the power adapter and switching power supply characteristics
Switching power supply features:
It is through the circuit control switch tube for high-speed pass and cut off, the DC into high frequency AC power provided to the transformer to transform, resulting in the required one or more groups of voltage. The reason for the conversion to high-frequency alternating current is that the efficiency of high-frequency AC in the transformer transformer circuit is much higher than that of 50HZ. Therefore, the switching transformer can be made very small and it is not very hot at work and the cost is very low. For the high frequency that switching power supply does not make sense.
Power adapter features:
Power adapter manufacturers to produce power converters (both AC to DC), mostly from the AC into DC, and then through the computer, it is not able to protect the computer, but the computer inside the storage of power storage (also called the charger), so in When the power failure can protect the computer.
Switching power supply and adapter are switching power supply, by the high-frequency switch and its control circuit. The adapter power supply is a regulated switching power supply, switching power supply charger with a float function, the voltage is smaller with the current becomes larger, after the only voltage and no current.
Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop. Extensive support in the phone son machine, game consoles, language repeaters, Walkman, notebook computers, cellular phones and other equipment.
