Abstract
An unbalanced three-phase power supply device of the present disclosure includes: a control circuit including a voltage command generation unit and a pulse modulation signal generation circuit; and a main circuit including a DC power supply, a three-phase inverter device, and a three-phase transformation device, in which the control circuit and the main circuit output, from the three-phase transformation device, an external zero-phase-containing unbalanced three-phase voltage including an external U-phase voltage, an external V-phase voltage, and an external W-phase voltage having phases, frequencies, and amplitudes respectively corresponding to phase command values and amplitude command values of a U-phase, a V-phase, and a W-phase of a predetermined zero-phase-containing unbalanced three-phase voltage of unbalanced three-phase voltage information received by the voltage command generation unit. The DC power supply, the three-phase inverter device, and the three-phase transformation device have respective forms and a mutual connection relationship that can output a zero-phase component.
