Abstract:
Provided is an AC-DC conversion device capable of making a small and inexpensive
system even in the case of an instantaneous low compensation capacity ≥
a load leveling capacity. The conversiondevice is constituted by connecting
a fast switch between the commercial power source and a load and by connecting
a PCS having a power storage unit, an AC-DC converter and a linking transformer
