Abstract

The invention provides an optical network hybrid power supply uniterruptable power supply having a function of correcting a power factor on a network side, relates to the field of transformation of electrical energy, and solves the problems that the conventional used uniterruptable power supply has large harmonic pollution and cannot continuously operate for a long time. The power supply comprises an energy storing capacitor, a first diode, a second diode, a control component, a charge-discharge control unit, a power factor correction circuit and a solar battery module, wherein the output end of the power factor correction circuit is connected with an anode terminal of the first diode; a cathode terminal of the first diode is simultaneously connected with one end of the energy storing capacitor, a cathode terminal of the second diode, the output end of the charge-discharge control unit and the input end of the control component; an anode terminal of the second diode is connected with the output end of the solar battery module; and the other end of the energy storing capacitor is simultaneously connected with the input end of the power factor correction circuit, the input end of the charge-discharge control unit, the input end of the solar battery module and the input end of the control component. The power supply can be widely used in the field of the transformation of the electrical energy.

Description

technical field

[0001] The invention relates to the field of electric energy conversion. Background technique

[0002] Uninterrupted Power Supply (UPS) for short, is a power supply that can provide short-term continuous power supply when the main power supply fails. It has important practical value in various industries and fields, especially important systems, important departments and important electrical equipment with strong real-time performance. UPS power supply is mainly divided into standby type, online type and standby interactive type. Among them, the output voltage of the online implementation scheme is not affected by the voltage quality of the grid side, and the characteristics of high output voltage quality have been more and more widely used in actual systems. . Compared with the United States and Europe, my country's independent design and manufacturing capabilities of UPS technology and related products are still at a relatively backward level. The master...
