Ripple is a type of electrical noise that is present in all power adapters. It is caused by the constant switching of the power adapter's internal circuitry, which results in a fluctuating current. Ripple can cause serious damage to sensitive electrical components, such as microprocessors and other integrated circuits. It can also cause instability in the power output, leading to problems with the performance of the device.
When the output of the power supply is working, a phenomenon of fixed frequency fluctuation caused by the switching of the power supply itself, the ripple is generally synchronized with the switching frequency of the power supply, and is generated by the charging and discharging of the capacitor, PWM adjustment, etc.
In a word, it’s an AC interference single on the DC signal, and the frequency of it is the same as the frequency of switching.
Nowadays, power adapters are widely used in our daily life, and the quality of them has a great influence on our life. One of the most important factors that affect the quality of power adapters is the ripple of them. So why we need to reduce ripple for power adapters?
Firstly, the ripple of power adapter will bring interference to the connected device. If the ripple of the power adapter is too high, it will cause interference to the connected device and affect the normal operation of the device. Therefore, the ripple of power adapter should be reduced as much as possible to ensure the normal operation of the device.
Secondly, high ripple will increase the power loss of the power adapter. High ripple will cause the voltage to fluctuate, so the power adapter will consume more power to maintain the same output voltage, which will increase the power loss and reduce the efficiency of the power adapter.
Thirdly, high ripple will also cause noise. When the ripple is too high, the connected device will produce a lot of noise, which will disturb people's normal life.
Reducing ripple for power adapters is important to ensure that the device or equipment being powered is supplied with a clean, stable voltage. Ripple is a type of electrical noise that can interfere with the performance of the device or equipment. It can cause equipment malfunctions, system errors, and even damage components. Reducing ripple helps to ensure that the device or equipment is receiving a steady, reliable voltage.
