Abstract
A multilevel converter includes a first arm connected between a positive voltage terminal and an alternating-current terminal and a second arm connected between the alternating-current terminal and a negative voltage terminal. Each of the first and second arms includes a plurality of cascaded unit cells. Each unit cell has a capacitor charged to a direct-current voltage and outputs a voltage across terminals of the capacitor or 0 V. The plurality of unit cells as being helically cascaded implement a reactor.
