【正文】 MATLAB 仿真結(jié)果表明，本文設(shè)計(jì)方案實(shí)現(xiàn)了蓄電池儲(chǔ)能 /釋能控制，實(shí)現(xiàn)了 UPS 系統(tǒng)能量供需的不間斷性的要求。 Abstract With the development of modern industry, power supply work load more and more plex, especially large electricity load, the power supply quality requirements more stringent. If the power supply is power grid of external factors interference can lead to power supply quality anomalies, lead to meet in the power grid of the equipment, the lost data, occur because downtime, damage and serious consequences, directly affects the normal work of the user, economic damage or other serious accidents. UPS is a kind of can provide continuous load of electric power, power supply systems, from the initial offer has a single function reserve time to today provide backup power quality time and improve the double function, in the protection of data, and improve the quality of power, power cuts and power grid to prevent pollution harm party and such as user has a very important role. Based on the analysis of the online threephase UPS work based on principle, design and simulation applies to the online threephase UPS charging and discharging circuit and improve the load power supply stability. The current reversible posite chopped circuit, design of a threephase UPS system of online battery energy storage/release can be control of both DC/DC converter。 When the utility anomalies, storage battery to load release energy, twoway DC/DC converter working in Boost circuit model. In this paper, according to the requirements of the stable power supply voltage of the load, pleting the twoway DC/DC converter closedloop control parameters design. MATLAB simulation results show that the design scheme realized battery energy storage release can be control, realize the UPS system of supply and demand of intermittent not energy requirements. Key words : UPS。 Bidirectional DC/DC converter。 Charge and discharge. 目 錄 摘要 ......................................................................................................................
