Title:
MULTILEVEL POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/230107
Kind Code:
A1
Abstract:
First to N-th common portions 11 to 1N (N is an integer of 2 or more) common to each phase are connected to a DC link capacitor DCC common to each phase. M-phase (M is an integer of 2 or more) phase modules 31 to 3M are connected to the N-th common portion. 21-1 to 2N-1 basic cells are connected to the first to N-th common portions 11 to 1N, respectively. This makes the number of divisions of the DC link capacitor equal to 2 or less and provides a multilevel power conversion device having the number of voltage levels of 5 or more.
