The power adapter is a device for converting the power adapter for small portable electronic devices and electronic devices.
What difference do you know between a power adapter and a charger?
Why do we use adapters?
What is the function of the power adapter?
various ingredients
1.power adapter: It is an electronic device for small portable electronic devices and power conversion devices. It consists of housing, transformer, inductance, capacitor, control chip, circuit board etc.
2.Charger: It consists of stable power adapter (mainly stable power adapter, stable working voltage and sufficient current) and necessary control circuits such as constant current, voltage limitation and time limitation.
different current modes
1.power adapter: from AC input to DC output, display power, input and output voltage, current and other displays.
2.Charger: It uses a charging system with constant current and voltage limitation. The general charging current is about C2, that is, a 2-hour charging rate is used. For example, a charging rate of 250 mAh for a 500-mAh battery is about 4-hour.
1.The efficiency of filtering is greatly improved, which greatly reduces the capacity and volume of filter capacitor.
The operating frequency of the switching power adapter is generally over 50 kHz, which corresponds to more than 1000-times the linearly regulated power adapter, whereby the filter efficiency after rectification is almost 1000-times higher. Also up to 500x. Under the same output waveform voltage, the capacity of the filter capacitor when using the switching power adapter is only 1/500 or 1/1000 of the filter capacitor in the linearly controlled power adapter.
2. Wide range of voltage control.
The output voltage of the switching power adapter is regulated by the tactile cycle of the excitation signal, and the change in the input signal voltage can be compensated by frequency modulation or width modulation. In this way, a relatively stable output voltage can still be guaranteed with strong changes in the mains frequency mains voltage. Therefore, the voltage control range of the switching power adapter is very wide and the voltage control effect is very good.
The main function of the power adapter is the power adapter. The power adapter is a device for converting the power adapter for small portable electronic devices and electronic devices. It generally consists of a housing, a power transformer and a rectifier circuit. Depending on the output type, it can be divided into AC output types. and DC output type; Depending on the connection method, it can be divided into wall type and desktop type.
There are many types of interfaces of power supplies, which are divided into diameter and outer diameter. Most sold on the market have a diameter of 3.5mm and some have a diameter of 2.5mm. Some notebook computers need to use a special power adapter, and the interface is relatively small. The interface of some power supplies is the LPT interface, and the extension interface of the parallel communication protocol is particularly fast in transmission.
