PGS/ISEA holds the German-Korean Symposium on Power Electronics From June 20th to Jun 23th at E. ON ERC in Aachen. The Symposium focused on three main topics: the state-of-the-art topologies and devices in the MVDC grid, charging strategies for electric vehicles, and control strategies for electric machines.
The German-Korean Symposium on Power Electronics took place in Aachen from June 20th to Jun 23th. The Symposium focused on three main topics: the state-of-the-art topologies and devices in the MVDC grid, charging strategies for electric vehicles, and control strategies for electric machines. At the symposium, Prof. De Doncker’s presentation about the high-power density DC-DC converters provides the key vision for the development of power electronics in the next generation. Prof. Sungmin Kim from Seoul National University, the partner of FEN, gave a presentation about the “Converter for MVAC/DC to LVDC conversion system”. First, he introduced the modular converter for the MV grid, which features a high-speed communication link, high-performance control, and multiple control objectives. He compared a centralized control with a decentralized control for the modular converter. With decentralized control, the communication link is less dependent and the control scheme is simpler. Prof. Seung-Ki Sul presented about the direct MTPA Tracing control of position Sensorless IPMSM including low-speed regions. This method does not require the conventional sensorless position estimation by full–speed range MTPA tracking control. It minimizes the interference of harmonics and enhances dynamic performance.
