The instability of the network and storage nodes may lead to the failure of the storage process in the network storage environment. In this paper, we establish the realibility model of the storage node availability, and the probability model of a success file block storage process, give the Store-After-Partition Strategy, compare the probabilities of a(More)
This article presents a novel topology of dynamic voltage regulator using transformer and PWM AC chopper. The proposed voltage regulator employs an ac chopper converter to generate compensation voltage and uses the transformer to isolate the power converter from the load. When input voltage sags and swells occur, the output voltage can be regulated by(More)
