Abstract:

Provided is a power conversion device which is small and can be configured inexpensively. The power conversion device (100) is provided with first to third power conversion cells (20-1 to 20-6) connected between a primary-side system (60) and a secondary-side system (70) which is an N-phase (N is a natural number of 3 or more) alternating-current system, each of the cells having a pair of primary-side terminals (25, 26) and a pair of secondary-side terminals (27, 28). The primary-side terminals of the first to third power conversion cells (20-1 to 20-6) are connected in series and connected to the primary-side system (60). The secondary-side terminals of the first power conversion cells (20-1, 20-2) are connected to portions relating to the secondary-side first phase (secondary-side V phase). The secondary-side terminals of the second power conversion cells (20-3, 20-4) are connected to portions relating to the secondary-side second phase (secondary-side U phase). The secondary-side terminals of the third power conversion cells (20-5, 20-6) are connected to portions relating to the secondary-side third phase (secondary-side W phase).
