Embodiment Construction

[0017] Such as figure 1 , 2 As shown, a multi-standard UPS power supply of the present invention is mainly composed of a three-way single-phase PFC rectifier circuit 1, a three-way single-phase inverter circuit 2, a centralized bypass part 3, a storage battery pack 4, a DSP processor 5 and a system selection input device 6, wherein the user inputs a user instruction to the DSP processor 5 through the system selection input device 6, and after the user instruction is decoded and analyzed to obtain the required control parameters, the DSP processor 5 controls the corresponding output voltage and output of the inverter. phase, output frequency, and finally output the inverter drive signal to the three-way single-phase inverter circuit 2, and output the sine wave alternating current through the centralized bypass part 3 after being inverted by the inverter.

[0018] Such as figure 1 As shown, the three-way single-phase PFC rectifier circuit 1 is composed of three single-phase PF...

Abstract

A multi-system UPS power supply is prepared as inputting user command to DSP processor by user through system selection input unit, controlling relevant output voltage and output phase as well as output frequency by DSP processor after required parameter is decoded out from said user command, outputting contra-variant driving signal to three-way single phase contra-variant circuit and outputting sine wave AC current through centralized bypass after said contra-variant driving signal is inverted by three-phase inverter.

Description

technical field [0001] The invention relates to a multi-standard UPS power supply and a method for realizing multi-standard selection. Background technique [0002] It has been nearly 40 years since UPS power supply was produced, and it is very mature in terms of technology. But from the perspective of users, usually one model cannot meet the power supply needs of all users. Different users have different requirements for various power parameters, such as input voltage, input frequency, output voltage, output frequency, number of input phases, number of output phases, etc., according to different power consumption environments. Therefore, there must be different products to meet different customer requirements, which brings a lot of inconvenience to UPS manufacturers and users. And as the power consumption environment changes, the user's model must be changed accordingly, which virtually increases the user's input cost. Contents of the invention [0003] The purpose of ...
