Since the DC stable low ripple power supply is generally formed by the AC power supply through rectification and voltage stabilization, it is inevitable that there are some AC components in the DC stable quantity.
Ripple Definition in Low Ripple Power Supplies
1. what is ripple?
In a power supply system, ripple refers to the AC component of the DC voltage output by the power supply. Simply put, it is the "ripple" or "fluctuation" in direct current ". This fluctuation may come from the conversion efficiency of the power supply itself, or fluctuations caused by external factors such as load changes, grid disturbances, etc. For electronic devices that require a stable DC power supply, the size of the ripple directly affects its performance and stability.
Ripple Points in 2. Low Ripple Power Supplies
In low ripple power supplies, manufacturers optimize the power supply design and adopt advanced power management technology to make the DC output voltage as close as possible to the ideal smooth DC. Such a power supply plays a vital role in sensitive electronic equipment, especially high-precision equipment, communication equipment and computers. Low ripple power supply can effectively reduce the impact of power fluctuations on equipment performance and improve the stability and reliability of equipment.
Hazards of 3. Ripple
If the ripple of the power supply output is too large, it may cause a series of problems for electronic equipment. For example, it may cause unstable operation of the circuit and affect the performance of the device; it may also cause the device to overheat and shorten the service life of the device; it may even cause electromagnetic interference (EMI) and affect the normal operation of other devices. Therefore, for electronic devices that require high precision and high stability, low ripple power is essential.
Application of 4. Low Ripple Power Supply
Low ripple power supplies are widely used in electronic equipment that requires high precision and high stability, such as communication equipment, computers, medical equipment, precision testing equipment and other fields. In these fields, the performance stability of the equipment is very important, so it is necessary to use a low ripple power supply to ensure the normal operation of the equipment.
In summary, the ripple in a low ripple power supply refers to the AC component of the power supply's output DC voltage. The low ripple power supply makes the DC voltage of the power supply as close as possible to the ideal smooth DC through optimized design and advanced power management technology, thereby improving the stability and reliability of the equipment. In electronic devices that require high precision and high stability, the application of low ripple power supply is very important.
