Power Supply Ripple and How to Minimize Ripple to the Lowest Level
The quality of the power supply output waveform significantly affects the performance, reliability, and safety of equipment. If components such as ripple, noise, and harmonics in the waveform exceed allowable limits, they can cause a series of issues.
Ripple is a common periodic fluctuation in the output waveform, primarily caused by the high-frequency switching action of switching power supplies. Excessive ripple leads to unstable output voltage, affecting the operational stability of equipment. Particularly for precision electronic devices such as computers and servers, it may cause logic errors or operational abnormalities.
At the same time, ripple current passing through the equivalent series resistance (ESR) of electronic components generates Joule heat, increasing component temperature and accelerating aging. For example, the lifespan of electrolytic capacitors significantly shortens under high temperatures, potentially leading to failure. Semiconductor devices such as MOSFETs may overheat due to increased switching losses, potentially causing threshold voltage drift or breakdown and burnout.
In signal processing equipment, power supply ripple can couple into signal paths, becoming a noise source and reducing the signal-to-noise ratio. Audio amplifiers may produce hum, communication equipment may experience increased bit error rates, and image sensors may generate noise, affecting signal restoration accuracy.
For high-precision measurement equipment, ripple can also introduce additional errors, affecting measurement accuracy.
Ripple and noise can also increase electromagnetic interference (EMI) in equipment, affecting surrounding devices through power lines or radiation. High-frequency noise may interfere with the timing of digital circuits, leading to data transmission errors.
In the long term, the continuous thermal stress caused by ripple reduces the overall reliability of equipment, increases failure rates, and may elevate the risk of leakage due to aging insulation materials, potentially leading to safety incidents such as overheating and fires.
To mitigate these negative effects, it is necessary to optimize power supply design, such as selecting filtering components with appropriate parameters, adopting soft-switching technology or RC snubber circuits, and ensuring proper PCB layout to suppress parasitic effects.
