This paper proposes a highly efficient drive method for an open‐winding induction machine with a single constant voltage source and a single capacitor. By focusing on the phase voltage of the open‐winding machine, which is determined by the phase difference and the dc voltage of each power converter, it is possible to control the peak value of the phase voltage by controlling the voltage of the capacitor. Thus, a reduction in the iron loss due to harmonic voltage in the open‐winding machine is expected. In the proposed method, the voltage of the capacitor is controlled by the difference between the two reference voltages of the power converter, which depends on the machine power factor and the phase difference of the power converter connected to both ends of the winding. Based on experimental results, the converter loss and the machine loss can be reduced by controlling the voltage of the capacitor in accordance with the machine speed using the proposed method.
