Abstract: A three-level power converter includes a direct current power supply unit including a filter capacitor connected between a high potential line and an intermediate potential line and a filter capacitor connected between the intermediate potential line and a low potential line, and a power conversion circuit that converts a three-level direct current voltage output from the high potential line, the intermediate potential line, and the low potential line into a three-phase alternating current voltage. A controller generates an imbalance signal representing an imbalance between a first capacitor voltage and a second capacitor voltage on the basis of values detected by voltage sensors, and generates a modulation signal for causing the power conversion circuit to perform a two-phase modulation operation on the basis of a superimposed signal obtained by superimposing the imbalance signal on a reference signal of the three-phase alternating current voltage.
