Abstract

Abstract:

In order to solve the problem that focused bypass type parallel UPS system phase-locked control complex,and low precision,according to the theory analysis and engineering conditions,this paper puts forward a second order phase locked control method and the control precision and harmonious wave characteristics are analyzed in detail.The experimental results show that the proposed method is simple and can effectively improve the synchronization control precision of parallel UPS system,which can restrain the circulation and ensure the stable operation of parallel UPS system.

Key words: focus bypass, parallel, phase lock loop, precision, harmonious wave charateristics
