An Active Thermal Control Method for AC-DC Power Converter with Sequence-based Control Approach

摘要

With the heightened development of semiconductor technology, power electronic devices have had a crucial role in power systems. They are employed in a different variety of applications, including but not limited to energy conversation and grid connection for renewable energy sources, motor drive systems in electric vehicles and industrial systems, and AC/DC power conversion in the ship power system (SPS). Especially, medium voltage DC (MVDC) distribution systems are highly interested in future ship power systems, therefore, power converter devices and their control systems will be commonly used in the ship system. Due to the limitation of weight and size of the power converter and its cooling system, a well-designed control system may reduce the required cooling system and improve the overall system performance. In this paper, we propose an active thermal management for power converter using model predictive control approach.
