Abstract

PURPOSE: To make a rated capacity of an emergency generator small by together with providing transformers of different output side phases for each no off power source device under parallel operation providing rush current limitting elements at a no off power source system (CVCF).
CONSTITUTION: Plural numbers of a no off power source device 10 are connected to a commercial alternating current and to an emergency generator 3 through a change over switch 1. A no off power source device 10 has short circuitting switches 7,8 and a rush current limitting impedance 6 and moreover has a rectifier use transformer 21. Secondary sides of transformers are connected so as each to have a phase different respectively, therefore input side harmonics are reduced. Also by a rush current limitting impedance a rush current is reduced, accordingly a capacity of an emergency generator can be made small sized.
