Research On System Of Delta Numeralization UPS

Owing to the data program input to a early computer are quite complex, Uninterruptible Power Supply come into being, which to avoid repetitive work under power failure, that whole data will lose in the work at the time of power failure, and input over again when the power supply recover.Nowadays, Uninterruptible Power Supply already play an important role in computers, information network, bank, hospital as well as aviation, along with more and more applications of UPS, the requirement for its performance get improved.The transformation technique design and its realization of the Delta uninterruptible power supply (UPS) are researched in the dissertation, This design According to the requisition of numeralization, miniaturization, greenness and high frequency, in order to gain the certain theories and technique foundations of the new power supply (UPS).First of all, this article introduced the source and meaning of the design, actuality research of inside and outside, as well as mostly content and method. Next, from several aspects introduced the basic technique of the Delta uninterruptible power supply and chose the Delta switch technique for key part of the circuit. Following analyze and compared the digital control policy which uses in common, finally select the numeralization PID control. This article focus on designed the structure and parameter of main circuit, control circuit and assist circuit, as well as elected the various types of control chip, and debug to pass on the hardware based on TMS320F2812 DSP, realized total numeralization controlation of UPS. This article designed the software of system when the hardware circuit finished, especially the main converter, and the system software can realize each functional module in the UPS.This design analysis particularly from each part circuit for function realization to the whole system principal, and via a great lot of analysis, simulations and experiments has verified the system's feasibility an advantage. The research in the dissertation, to some extent, has paved a way for the further research, improvement and application in the digital control of UPS.
