1. The Impact of Input Voltage Range. When the input voltage is too high, certain components may be damaged due to excessive applied 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 spot scanning time. For example, a digital voltmeter requires a stable internal power supply to ensure voltage and digital conversion accuracy.
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 drop, thereby affecting the operation of another load. Another example is an amplifier with a high gain coefficient. When the current in a certain stage (power stage) changes, it can affect the voltage change of the power supply, which may affect the previous stage, forming a positive feedback loop, leading to self-oscillation and inability to operate normally. 36V aviation power supply, 400HZ variable frequency 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 DC stable power supplies significantly affects communication quality. Interference from alternating noise during conversations hinders the clarity of long-distance calls. For example, the hum from speakers, the black horizontal lines on TV images, and uneven image lines directly impact the audio-visual experience.
5. The impact of overvoltage on the output end. For example, when the output voltage of a DC stabilized power supply exceeds the rated voltage of the integrated circuit by 30%, it may cause extensive damage to the integrated circuit.
6. The Impact of Brief Power Outages. For instance, local telephone communications must not be immediately disconnected, as this could interrupt global communication, leading to major incidents. As another example, when computers and the like use AC power, an uninterruptible power supply should be used.
