This FAQ reviews developments in power electronic systems that can produce step function improvements in performance. It looks at multiplexing uninterruptible power supplies (UPS), the benefits of using deep reinforcement learning (DRL) with distributed renewable energy generation, several control strategies for voltage source converters (VSCs) in distributed generation (DG) and microgrid systems, and the possibility of using distributed power factor correction (PFC). Power converter efficiency is affected by the loading factor, and multiplexing power supply units (PSUM) has been designed to improve loading factors and control redundancy levels.
