摘要： A power conversion device includes a switched AC-to-DC converter circuit coupled to a device input and a switched DC-to-AC converter circuit coupled to the switched AC-to-DC converter circuit and a device output. The switched AC-to-DC converter circuit and the switched DC-to-AC converter circuit are configurable for multi-level step-up and/or step-down conversion.

摘要： A multilevel converter-based, intelligent, universal transformer includes back-to-back, interconnected, multi-level converters coupled to a switched inverter circuit via a high-frequency transformer. The input of the universal transformer can be coupled to a high-voltage distribution system and the output of the universal transformer can be coupled to low-voltage applications. The universal transformer is smaller in size than conventional copper-and-iron based transformers, yet provides enhanced power quality performance and increased functionality.
