1. Impact of Input Voltage Range. When the input voltage is too high, certain components may be damaged due to excessive voltage or power consumption. When the input voltage is too low, the performance of some components may degrade, and they may even fail to operate.
2. The impact of voltage instability. For instance, the oscilloscope's DC stable power supply must be stable to ensure the sensitivity of deflection and the accuracy of the light spot scanning time. For example, a digital voltmeter requires a stable internal power supply to ensure voltage accuracy in digital conversion.
3. The impact of internal resistance in DC stable power supplies. For instance, when the internal resistance of a power supply is high and the current of a load increases, the voltage of the DC stable power supply will decrease, thereby affecting the operation of another load. Another example is an amplifier with a high gain factor. When the current in a certain stage (power stage) changes, it can affect the voltage of the power supply, which might impact the previous stage, creating a positive feedback loop, leading to self-oscillation and failure to operate normally. 36V aviation power supply, 400HZ frequency conversion power supply, 115/200V power supply, 27V DC power supply, 400HZ power supply, aviation power supply
4. The Impact of Power Noise. For instance, the noise from a DC stabilized power supply significantly affects communication quality. Interference from alternating noise during conversations hinders the clarity of long-distance calls. For example, the hum in speakers, horizontal black lines on TV images, and uneven image lines directly impact the audio-visual experience.
5. The impact of overvoltage on the output terminal. For instance, when the output voltage of a DC regulated power supply exceeds the rated voltage of an integrated circuit by 30%, it may cause significant damage to the integrated circuit.
6. Impact of brief power outages. For instance, local telephone communications cannot be immediately shut down, as this would disrupt global communication and lead to major incidents. As another example, when computers and other equipment use alternating current (AC) power, an uninterruptible power supply (UPS) should be used.
