Important technical indicators of DC power supply

1) Voltage adjustment coefficient and voltage adjustment rate: The voltage adjustment coefficient refers to the relative change of the input voltage resulting in a relative change of the output voltage when the load current and the ambient temperature remain unchanged.
The voltage adjustment rate is the relative change of the output voltage when the input voltage becomes 10% relative. Both the voltage adjustment rate and the voltage adjustment rate illustrate the influence of the input voltage change on the output voltage.
So only one of them needs to be tested.

2) Output resistance and current adjustment rate: The output resistance is equal to the output resistance of the amplifier, which is the value of the output voltage variation and output current variation when the input voltage is constant.
Current adjustment rate: The relative change value of the output voltage generated when the output current changes from 0.
Both output resistance and current regulation account for the effect of changes in load current on the output voltage, so only one needs to be tested.

3) Ripple voltage: the AC voltage component superimposed on the output voltage.
Use an oscilloscope to observe the peak-to-peak peak value, which is generally at the millivolt level.
You can also use an AC millivolt meter to measure the effective value, but there is a certain error because the ripple is not a sine wave.



Application of DC power supply

The DC power supply cosmic undertaking shoulders a special national mission.
Aerospace communication systems have particularly high timeliness requirements for specificity and confidentiality.
The reliability of the communication power supply is the primary task of the aerospace communication department and an important guarantee for the safe operation of the communication system.
At present, cosmic system communication bureaus (stations) generally use UPS systems as the main power supply of IT equipment, which overcomes system interruptions caused by mains power interruptions.
However, the failure of the UPS itself, or even the redundant system at the same time, sometimes leads to network communication accidents, causing social impact and considerable economic losses.
