Important Components of the Power Adapter
1. The information voltage scope of the power adapter
At the point when the information voltage of the exchanging power supply changes, the information voltage variety range that keeps the result qualities unaltered is kept up with. The more extensive this reach, the more grounded the capacity of the power supply to adjust to changes in the outside mains and the more extensive the functioning scope of the exchanging power supply. It is connected with the blunder speaker inside the exchanging power supply, the increase of the inspecting input change circuit and the change scope of the obligation cycle.
As of now, the information voltage variety scope of the exchanging power supply has reached 90V-270V, which can save the 110V/220V switch on numerous electrical apparatuses.
2. The voltage guideline pace of the power adapter
Voltage guideline, otherwise called voltage solidness, is the relative change in yield voltage when the result current remaining parts unaltered (the heap doesn't change) and the information AC working voltage changes.
This specialized marker is utilized to check whether the dependability of the result voltage of the exchanging power supply meets the necessary particulars under the most obviously terrible power supply voltage climate.
3. The ongoing guideline pace of the power adapter
The ongoing guideline rate, otherwise called the heap guideline rate, is the overall difference in the result voltage when the information AC voltage is appraised, (for example, 220VAC) and the result current changes from the base worth of 0 to the most extreme worth.
This marker is utilized to confirm whether the result voltage dependability of the exchanging
power adapter meets the expected details under the most terrible burden climate.
4. The result obstruction of the power adapter
There is the proportion of the adjustment of result voltage to the adjustment of result current. The more modest the proportion is, the more modest the difference in the result voltage of the power supply with the size of the heap and the better the voltage guideline execution.
5. Change effectiveness of the power adapter
There is the proportion of result power to supply input power of a power. The higher the proportion, the higher the change proficiency, the more modest the size of the exchanging power supply and the higher the unwavering quality. As of now, the proficiency of exchanging power supply can arrive at over 90%.
6. Swell voltage of the power adapter
Since the voltage guideline cycle of the exchanging power supply is a course of nonstop inspecting and criticism change, there will be a superimposed and fluctuating wave voltage on the result DC voltage, that is to say, the result swell voltage. The more modest the worth, the better the result qualities. There are two methods for communicating the wave: one is the viable worth of the result swell voltage, the other is the pinnacle worth of the result swell voltage.
The particulars of the general exchanging power supply are expected to be under 1% of the result DC voltage and its transmission capacity is 20Hz-20MHz or other higher frequencies, for example, 100MHz. In brutal conditions, the result DC voltage of the exchanging power supply of the China
power adapter in addition to the commotion wave shouldn't surpass the result high and low voltage limits (Min worth and Max esteem). If not, it might cause the power supply voltage to surpass or be lower than the functioning voltage of the rationale circuit, (for example, TTL circuit) and glitch, which will additionally cause an accident.
