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.

The digitalization of the energy system is a key element of the energytransition. In October 2022, the European Commission released the Digitalizationof Energy Action Plan which gives guidelines on how to achieve this goal. Nomatter which approaches we take, digitalization is a complex process that hasto be anyway implemented in a short time to really support the overarching goalof decarbonization. For this reason, cooperation is critical both on theresearch side and on the business side.
