発明の名称 (英語) MULTILEVEL POWER CONVERTER AND METHOD FOR CONTROLLING MULTILEVEL POWER CONVERTER
発明の概要(英語) A multilevel power converter (1) provided with a transformer (14) having AC input/output terminals (T1-1, 2) on a primary side and an intermediate terminal (T2-3) on a secondary-side coil, a first and a second arm (12-P, N) being connected to both ends (T2-1, 2) on the secondary side and being provided with a plurality of cascade-connected unit cells (11-1, ...M) having a semiconductor switch, a DC capacitor (C), and an input/output terminal for a charge/discharge current, and a DC power supply (Vdc) being connected to the intermediate terminal (T2-3), the free end of the DC power supply (Vdc) and the first and second arms (12-P, N) being connected at an arm joint part (13); wherein circulation currents (iZP, iZN) flowing through the first arm (12-P) and the second arm (12-N) are separately defined, and the average DC voltage value in each arm is independently controlled, whereby the need for arm balance control is obviated.
