Adjustable Switching Power Supply Workflow
The supplier of adjustable switch switches, the supplier of power supply, is the supplier of input AC power supply. After rectification and filtering, the supplier of AC power supply is replaced with DC power, which is then converted into high-frequency AC power and supplied to the supplier of the transformer for voltage transformation, thereby generating the required set or multiple sets of voltage.
brief introduction
Adjustable switching power supply refers to the process of converting the input AC power supply into DC power through rectification and filtering, and then converting it into high-frequency AC power to provide it to the transformer for voltage transformation, thereby generating the required set or sets of voltages! The reason for converting to high-frequency AC power is that the efficiency of high-frequency AC in the transformer circuit is much higher than that of 50HZ. Therefore, switching transformers can be made very small and not very hot when working!! The cost is very low. If 50HZ is not converted to high-frequency, then the switching power supply is meaningless.
Workflow of Adjustable Switching Power Supply
Power supply → Input filter → Full bridge rectification → DC filtering → Switching transistor (oscillation inverter) → Switching transformer → Output rectification and filtering.
Detailed content
1. Adapt to the needs of production development
The original power supply can be utilized, and on this basis, the number of modules can be flexibly increased or reduced, and the current can be increased or reduced to improve the utilization rate of the equipment.
2. Improve production operation reliability
When designing the power supply, the N+1 mode is adopted. Under normal circumstances, all modules are involved in operation. If the equipment malfunctions, the power supply will not stop. The system will automatically reduce current operation and exit the faulty unit without affecting production.
3. Convenient maintenance
All module units are universal, and only a few module units need to be backed up to freely replace faulty modules, making maintenance relatively simple.
4. Digital control
Each module unit is controlled by a microprocessor as the core, mainly using software programs to achieve automatic current sharing and other control schemes. It has flexible control, high accuracy, fast dynamic response, fewer components used, and high reliability.
5. The entire power system adopts an intelligent overall circuit structure, achieving module hot swapping, current sharing control, fault detection, and fault information display functions, with a user-friendly interface.
