Adjustable switching power supply workflow
The supplier of the adjustable switch switch The supplier of the power supply is the supplier of the input AC power supply. The AC power supply is rectified and filtered and converted into DC power, and then converted into high-frequency AC power, which is provided to the transformer transformer supplier for voltage transformation, thereby generating one or more sets of voltages required.
Introduction
The adjustable switching power supply is that the input AC power supply is converted into DC by rectification and filtering, and then converted into high-frequency AC for transformer transformation, thereby generating one or more sets of voltages required! The reason for converting to high-frequency AC is that the efficiency of high-frequency AC in the transformer circuit is much higher than that of 50HZ. Therefore, the switching transformer can be made very small, and it is not very hot when working!! The cost is very low. If 50HZ is not changed to high frequency, then the switching power supply is meaningless.
Workflow of adjustable switching power supply
Power supply→input filter→full bridge rectification→DC filter→switching tube (oscillating inverter)→switching transformer→output rectification and filtering.
details
1. Adapt to the needs of production development
The original power supply can be used, and on this basis, the number of modules can be flexibly increased or decreased, the current can be increased or decreased, and the utilization rate of the equipment can be improved.
2. Improve the reliability of production operation
The power supply design adopts the N+1 mode. Under normal circumstances, all modules participate in the work. If the equipment fails, the power supply will not stop. The system will automatically reduce the current operation and exit the faulty unit without affecting production.
3. Easy maintenance
All modular units are common, only need to back up a few modular units to freely replace faulty modules, making maintenance relatively simple.
4. Digital control
Each module unit uses a microprocessor as the control core, and mainly uses software programs to realize automatic current equalization and other control schemes. It has flexible control, high precision, fast dynamic response, few components used, and high reliability.
5. The entire power supply system adopts an intelligent main line structure to realize module hot swapping, current sharing control\fault detection\fault information display functions, and the user interface is intuitive and friendly.
