Document Type and Number:
WIPO Patent Application WO/2014/192084
Kind Code:
A1
Abstract:
A power convertor is configured by parallel connecting of chopper circuits (3a, 3b) which are each configured from a reactor (4a, 4b), a switching element (5a, 5b), and a backflow preventing element (6a, 6b) and chop and boost the output from a rectifier (2) that rectifies the AC voltage from an AC power source (1), the power convertor comprising: an AC switch (12) disposed between the AC power source (1) and the rectifier (2); an AC reactor (13) disposed between the AC power source (1) and the rectifier (2) and connected in parallel with the AC switch (12); and a switching control unit (10) for controlling the operation of switching elements (5a, 5b) and the AC switch (12).
