Abstract

The invention relates to an intelligent power supply which belongs to the technical field of electronic circuits. The intelligent power supply comprises an input circuit, a conversion circuit, a voltage stabilization circuit and a USB interface. The input circuit, the conversion circuit, the voltage stabilization circuit and the USB interface are connected in sequence, and the input circuit is connected with the city power. The conversion circuit is used to convert 220V alternating current into first direct current with the voltage value of a first threshold and transmit the first direct current to the voltage stabilization circuit. The voltage stabilization circuit is used to convert the first direct current into at least two paths of second direct current and output the second direct current to the USB interface, wherein the voltage value of the second direct current is a second threshold less than the first threshold. The intelligent power supply can output at least two paths of direct current at the same time, which solves the problems of inflexible power supply and inconvenient use of a traditional power supply. The USB interface is used, which greatly simplifies the wiring ofa line. The intelligent power supply is plug and play without professional wiring, and has good applicability.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to an intelligent power supply. Background technique [0002] With the development of industry, agriculture and technology, almost all industries have been electrified. In many applications, the power supply undertakes the task of providing power supply for systems such as signals, controls, and sensors, and requires 24-hour uninterrupted work. These occasions are usually powered by grid AC input or DC bus, and the power supply required by loads such as chips, display devices, sensors, etc. is mostly low-voltage DC, and different loads require different DC voltages. If a host is connected to several types of digital sensors with different voltages, each sensor must be powered by a professional power supply, which will result in the disadvantages of numerous equipment, difficult construction, and inflexible use. Contents of the invention [0003] In view o...
