Problems solved by technology
[0002] The voltage input range of the existing power supply system is small, which cannot adapt to the working conditions that require a large voltage adjustment range
In the case of high-voltage input, the entire system has to bear a large load, which is likely to cause overvoltage and overheating, and cannot be protected, which will affect the safety and stability of the power system
At the same time, due to the interference of external input, the voltage transformation process is affected, making the voltage transformation process unstable, resulting in high cost, low efficiency, poor working stability, and insufficient reliability guarantee of the power supply system.

The invention discloses a power supply system which can be operated to supply electric power to a load circuit. The power supply system comprises a power supply source, an overload protective unit, a noise reduction unit, a rectification filtering unit, a transformation unit and an output unit, wherein the power supply source can be operated so as to supply the electric power through multiple power supply ends; the overload protective unit can cut off input electric power of the power supply source in case of overload, overheating and overvoltage; the noise reduction unit can eliminate interference signals; the rectification filtering unit can converts AC power supplied by the power supply source into DC power; the transformation unit can stabilize voltage, automatically adjust the voltage through feedback processing and supplies the voltage provided by the power supply source to the output unit; and the output unit supplies the electric power to the load circuit and feeds output signals back to the transformation unit so as to realize closed loop control. According to the invention, the power supply system can effectively isolate and eliminate signal interference, ensures stable transformation operation, and improves the work reliability of the power supply system.
Description
technical field [0001] The invention relates to the technical field of electric power, in particular to a power supply system. Background technique [0002] The voltage input range of the existing power supply system is small, and cannot adapt to the working conditions that require a large voltage adjustment range. In the case of high-voltage input, the entire system has to bear a large load, which is likely to cause overvoltage and overheating, and cannot be protected, which will affect the safety and stability of the power system. At the same time, due to the interference of external input, the voltage transformation process is affected, making the voltage transformation process unstable, resulting in high cost, low efficiency, poor working stability, and insufficient reliability guarantee of the power supply system. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a power supply system, the purp...
