The Role of DC Voltage Regulators
DC regulated power supply plays a very big role in daily production and life, compared to the various electronic equipment within the machine power supply, DC regulated power supply has a very great superiority, electronic equipment within the machine power discharge is not stable, will have a certain impact on the electronic equipment, the following instrumentation world network of experts to give you an introduction to the important role of DC regulated power supply.
Most of the electronic equipment each of the function of the in-flight power supply is through the unidirectional conductive components will be converted to DC, and with energy storage components composed of a variety of filtering circuits to filter out the pulsating components in the DC, but these functions still can not meet the requirements of some of the electronic equipment on the DC regulated power supply, which will have an adverse effect on the work of the electronic equipment, and its impact has the following aspects:
1, the impact of the input voltage range, when the input voltage is too high, it will make some components of the added voltage is too high or consume too much power and damage, when the input voltage is too low, but also will make some components of the performance degradation, and even can not work.
2, the impact of voltage instability, for example, the oscilloscope power supply must be stable to ensure that the light point of the deflection sensitivity, scanning time and other accurate; and, for example, the digital voltmeter requires an extremely accurate internal stable power supply to ensure that the voltage / digital conversion accuracy.
3, the impact of over-voltage output, for example, DC regulated power supply output voltage beyond the rated voltage of the integrated circuit of more than 30%, may cause extensive damage to the integrated circuit.
4, the impact of brief power outages, for example, municipal communications can not be instantaneous power outages, otherwise the global communications interruptions, resulting in major accidents; and, for example, computers and other AC power supply, AC uninterruptible power supply should be used.
This shows how important the role of DC regulated power supply in electronic equipment, can completely eliminate these effects, the working process of electronic equipment plays a very large maintenance role.
