Outline of Research Activities

Our research interest includes power converters and motor drives in power electronics field. The power electronics is an academic and technical field that focuses on power conversion using semiconductor devices. The most typical power converter is an inverter, which is widely employed as a motor drive system to various applications such as a high-speed train, a local railway, an electric vehicle, a hybrid vehicle, an elevator, an escalator, a robot, an air-conditioner and more. All these applications contribute to save system energy and to make control performance more sophisticated.
