1. Poor stabilityOne of the common problems with switching power supply is their poor stability. Due to the use of switching tubes or transistors for switch control in switching power supplies, electromagnetic induction may occur when the switching tubes or transistors are turned off, resulting in a sharp change in inductive current. This type of electromagnetic induction can cause the problem of instantaneous sudden changes in output voltage, resulting in significant fluctuations in the output voltage of the switching power supply.2. Serious EMI interferenceAnother disadvantage of switching power supply is that their EMI (electromagnetic interference) interference is more severe. Due to the high-frequency switching dynamic characteristics of switching power supplies, a large amount of high-frequency noise may be generated, which can easily interfere with surrounding electronic devices and signals, thereby affecting the output quality of audio, video, and other aspects.3. Relatively h...

Nowadays, everyone's smartphones have already used fast charging. Except for iPhones, the charging efficiency of domestic smartphones has reached over 66W. Nowadays, domestic smartphones have started to focus on fast charging. Recently, when they added a 100W fast charging, Redmi made a 300W fast charging. The fast charging market can be said to be neck to neck competition, with no one letting anyone down.But some people's mobile phones may not have such high charging efficiency, so can a 65W charger charge a 30W phone?As for the daily use of mobile phone chargers, mixing them up is already the norm. Manufacturers have already considered this when designing mobile phones, so there is no need to worry too much about it. At present, legitimate chargers are equipped with smart chips that can automatically recognize the power supported by the phone and intelligently allocate the appropriate current.However, it may not necessarily be fast charging. The charger and phone support the same fa...
Nowadays, laptop power supplies usually use the Type-C interface, which is the same charging head as the phone interface. However, sometimes we often forget to bring a phone charger when working. If the phone runs out of battery, can we use a laptop charger to charge it?Some people think it's possible because after all, the interfaces are the same. Both mobile phones and laptops are essentially lithium batteries, so they can naturally charge each other.But some people also believe that the power of a laptop charger is different from that of a mobile phone charger. Usually, the power of a laptop charger is greater than the output power of a mobile phone charger, which can damage the phone.So, can a laptop charger actually charge a phone?The answer is yes!If you are a careful netizen, you will find that the output power of laptop chargers is usually compatible with multiple voltages and currents, and their charging range is very wide. Taking Huawei laptop chargers as an example, their o...
solar charger controller functionSolar energy controllers, also known as solar charging controllers, are devices used to control where the electrical energy emitted by photovoltaic panels flows. It plays a very important role in solar photovoltaic power generation systems, with four main functions: limited current, overcharge protection, over discharge protection, and charging control.The function of current limiting protection is to ensure that the photovoltaic panels cannot be burned out due to overload operation; The function of overcharge protection is to protect the battery from damage when the voltage exceeds its standard voltage during charging; The function of over discharge protection is to prevent damage to the battery due to insufficient sunlight or high electricity consumption, resulting in low voltage; The function of charging control is to ensure the reasonable control of charging current, charging voltage, and charging time, so as to fully charge the battery and extend...
Solar chargers and solar controllers are two different devices with some differences in functionality and usage. A solar charger is a device that converts solar energy into electrical energy and stores it in a battery. Its core components include a solar panel, a battery, and a voltage regulating element. Its main function is to provide charging power for digital products such as smartphones, and can also provide electricity for other appliances. The advantages of solar chargers include environmental protection, energy conservation, portability, and long service life.A solar controller is a device specifically designed to control the charging of photovoltaic panels to batteries. It specifies and controls the charging and discharging conditions of the battery, and controls the electrical output of solar cell components and batteries to the load according to the power supply requirements of the load. The solar controller is the core control part of the entire photovoltaic power supply s...
