How important is a DC power supply? If categorized by technical specifications, what are the two types it can be divided into?
Technical specifications of DC power supplies can be divided into two main categories: one is the characteristic indicators, which reflect the inherent properties of DC power supplies, such as input voltage, output voltage, output current, and output voltage adjustment range; the other is the quality indicators, which reflect the performance of DC power supplies, including stability, equivalent series resistance, and the voltage variation of the power supply affected by current changes, which may affect the upstream stages and form a positive feedback loop, causing self-oscillation and preventing normal operation. The impact of power noise. Aeronautical power supply.
Power noise significantly affects communication quality, causing interference with alternating current sounds during calls, hindering the clarity of long-distance conversations. For example, humming in amplifiers, horizontal black bars on television images, and uneven image lines directly impact the audio-visual experience. The impact of overvoltage at the output. For instance, when the output voltage of a DC regulated power supply exceeds the rated voltage of an integrated circuit by more than 30%, it may cause extensive damage to the integrated circuit. The impact of brief power outages.
For instance, local telephone communication cannot experience instantaneous power outages, otherwise it would lead to a complete communication blackout, resulting in major accidents; similarly, when computers and other equipment are powered by AC supply, an uninterruptible power supply (UPS) must be used for AC power. 400Hz power supply
