要約(英語): Recently, power converters have been used in various electric machines, electric devices, etc. However, depending on the power sources, it is necessary to change the circuit topology to DC/AC, AC/DC, or AC/AC. In some applications such as the AC and DC dual locomotive, the power converter should be applicable for both AC and DC sources. For the applications, a converter that combines AC/DC and DC/AC is conventionally used. On the other hand, this paper presents a direct converter that is applicable for any source, utilizing the topological common point between the three-level inverter and the matrix converter and developing a modulation method. By using the modulation method and the matrix converter (MC) circuit, it is possible to achieve either DC/three-phase AC or three-phase AC/three-phase AC power conversion with a common duty calculation scheme. In addition, the proposed system allows two features. First, a control of the neutral point fluctuation, and second, dead time compensation is not required because current commutation can be applied for the three-level DC/AC. The numerical simulations and experiments have validated the conversion and enabled the authors to propose a new concept for a power conversion system.
