Description

technical field [0001] The invention relates to an intelligent high-frequency switching power supply, belonging to the technical field of power supplies. Background technique [0002] Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET, using electronic switching devices ( Such as transistors, field effect transistors, thyristors, etc.), through the control circuit, the electronic switching device is continuously "turned on" and "off", so that the electronic switching device performs pulse modulation on the input voltage, thereby realizing DC / AC, DC / DC voltage conversion, adjustable output voltage and automatic voltage stabilization. [0003] With the development and innovation of power electronics technology, switching power supply technology is als...

Problems solved by technology

[0003] With the development and innovation of power electronics technology, switching power supply technology is also constantly innovating. At present, switching power supply is widely used in almost all electronic equipment due to its small size, light weight and high efficiency. It is the rapid development of today's electronic information industry. An indispensable power supply method, especially in the surface treatment industry that requires high precision and a high degree of automation. With the rapid development of the domestic Internet of Things, industrial equipment is developing towards automation and modularization. Switching power supplies undoubtedly have Extensive use of space, the existing switching power supply can only display various numbers through a single mechanical or digital display mode, which cannot fully integrate various functions, which is not conducive to customer use, especially when high precision and intelligence are required. It cannot meet the needs of customers in a high-level use environment, and the manufacturing process is cumbersome, low in intelligence, poor in compatibility, large in size, single in function, not very convenient for customers to use and maintain, and high in maintenance costs.
