Abstract
An arm modulation command value calculation circuitry generates an arm voltage command value for each arm on the basis of a first voltage command value, a second voltage command value, and a third voltage command value, and generates an arm modulation command value for each arm on the basis of a result of comparison between the arm voltage command value for each arm and carrier waves corresponding to respective converter cells in each arm. A capacitor voltage balance control circuitry determines whether to insert or bypass each converter cell, on the basis of each arm modulation command value and arm current in each arm. A gate signal generation circuitry generates driving signals for semiconductor switching elements of the converter cells on the basis of commands for inserting and bypassing of the converter cells.
