· The difference between a bare power board and a complete power supply

1. Concept of bare board and complete power supplyThe bare board of switch mode power supply refers to a power board without a shell or packaging, which is an important component of the power supply technology research and development process. A complete power supply is a complete power product that encapsulates, casings, interfaces, filters, and other components of this bare board, which can be directly used for the power supply of various electronic devices.2. Differences in price and volumeThe bare board of the switch power supply is more affordable compared to a complete power supply due to the lack of accessories such as a shell or interface. Meanwhile, bare boards do not require an outer shell to secure components, and their volume is relatively smaller. Therefore, bare boards are suitable for application scenarios with strict requirements on price and volume, such as special heat dissipation conditions or limited installation space.3. Different usage scenariosThe comp...

· The advantages and principles of the open frame power supply module

The advantages of the open frame power supply module1. Shorten the development cycle. Open frame power supply can be obtained by matching the power supply with several discrete components.2. Users can also repeatedly stack or cross stack to form a modular combination power supply, achieving multi-channel output, greatly reducing the development cycle of the prototype.3. Small in size, it can integrate well with the product, reduce the volume of electronic products, and make electronic products better adapt to the widespread application of modern electronics.4. Stable work and higher efficiency. Compared with switch mode power supplies, the open frame power supply module adopts better electronic components and more advanced circuit design, making its operation more stable and reliable. At the same time, it effectively improves conversion efficiency and can effectively control efficiency and temperature under the same power.5. By using fixed processes such as glue filling, and directly...

· Introduction to the usage scenarios of Open Frame power supply

The basic principle of Open Frame power supplyOpen Frame power supply refers to a power supply device that has no casing, no output terminals, and only a circuit board. It can connect external output terminals, power switches, overcurrent protection and other components to achieve different output requirements of the power supply. Due to its high flexibility and ease of maintenance, it has been widely used in industrial automation control, LED lighting, communication and other fields.The basic principle of an Open Frame power supply is to convert the input voltage into a stable DC voltage for output through circuits such as rectification and filtering. The output voltage, current, and other parameters of the Open Frame power supply can be adjusted by adjusting the values of external components.The usage scenarios of Open Frame power supply1. Industrial automation controlIndustrial automation control requires stable input and reliable quality of power supply. And it needs to withstand...

· Completely depleting the battery of the phone before charging can indeed damage the battery life

There is always a saying about mobile phone charging: when the phone runs out of battery, it needs to be fully charged each time, which is beneficial for battery maintenance. Charging at any time can affect the battery life. In fact, these theories are quite outdated. So, how to charge your phone correctly?Destroy the charging posture of the batteryNowadays, smartphones, whether Android or iPhone, almost all use lithium-ion batteries. Assuming the battery is completely depleted, it will indeed have irreversible effects on the internal materials of the battery, shortening its service life.This is determined by the physical structure of existing batteries. When charging, the positive lithium ion inside the battery will reach the negative electrode through the channel of the intermediate separator. Combined with electrons passing through the external circuit of the battery from the positive electrode, the electrical energy of the power supply is converted into chemical energy inside the...

· The working principle and application of linear programmable power supply

Linear programmable power supply is a highly flexible power supply device, whose working principle is based on linear power supply technology and programmable control technology. Below, we will briefly explain its working principle and delve into its advantages in practical applications.Operational principleThe working principle of linear programmable power supply is mainly to meet the different voltage and current requirements of the device by adjusting the output of the power supply. Compared with traditional switching power supplies, the biggest feature of linear power supplies is to control the output voltage by changing the voltage drop or resistance size of the adjustment transistor. In this process, the adjusting tube is always in a linear working state, so it is named "linear power supply".Specifically, the core component of a linear programmable power supply is an adjustment transistor, which can be a variable resistor or a transistor with linear adjustment characteristics. W...
