Embodiment Construction

[0009] root figure 1 and 2 As shown, the CPU main control circuit (1) The automatic energy-saving regulated power supply is detected and sampled by the output detection circuit and the leakage and load detection circuit, and the detected data is sent to the CPU processor for processing in real time, and the CPU performs internal processing. Logical judgment, on the one hand, output the corresponding control signal to the drive circuit, so that the servo mechanism will act and switch to the winding of the corresponding energy conversion transformer to realize real-time voltage regulation and protection, so as to convert the unstable input AC voltage into a stable output The AC voltage is supplied to the electrical load. When the CPU detects that the mains voltage is within the high-precision standard voltage range and the load power is less than 5W, the energy-saving control circuit is started. On the other hand, it sends display and alarm signals, and displays the detected d...

Abstract

The invention relates to an energy-saving intelligent alternating current voltage stabilizing power supply, comprising a main control circuit, a driving circuit of a voltage stabilizing power supply, an autotransformer, a protection circuit, an energy-saving control circuit and the like. A novel intelligent high frequency PWM (pulse width modulation) integrated chip is taken as a control circuit, an Infineon high-end MOS (metal oxide semiconductor) tube is taken as the driving circuit of the voltage stabilizing power supply, and a diode and a super fast recovery diode form a clamping circuit to be taken as an MOS tube protection circuit; a modular power supply forms a distributed power supply system and is designed into an N+1 redundant power system in a parallel manner; an inlet wire terminal of a power supply is provided with a primary power supply noise filter, and interference of a power grid is inhibited; a tantalum electrolytic capacitor is taken as a power supply system absorption circuit and is connected with the power supply system in parallel; and an LCD (liquid crystal display) device displays parameters, an RS232 standard upper computer interface is arranged, and the energy-saving intelligent alternating current voltage stabilizing power supply provided by the invention has the advantages of fast input voltage response, fast load change response, overvoltage, undervoltage and overcurrent protection, automatic temperature detection, stable output frequency and low power consumption.

Description

Technical field: [0001] The invention relates to an AC stabilized voltage power supply, in particular to an energy-saving intelligent liquid crystal AC stabilized voltage power supply, which is suitable for high-precision current and voltage monitoring occasions. Background technique: [0002] In recent years, with the rapid development of electronic products, many electrical appliances have adopted different energy-saving technologies in power supply and equipment to varying degrees. The AC regulated power supply has been more and more widely used with its unique voltage stabilization and protection functions. It can not only stabilize the voltage and improve the quality of power supply, but also effectively protect the load, prolong the service life of the equipment, and assist users. Function to manage power supply. However, the loss of the regulated power supply itself has also attracted people's attention. How to minimize power loss, for this reason, it is necessary t...
