Investigation of a High-Frequency Link Single-Stage Asymmetrical Multilevel Converter for Grid Integration of Renewable Energy Systems
… a fifteen level high-frequency AC- link single-stage asymmetrical multilevel converter for grid integration is proposed. The single-stage conversion approach eliminates the DC-link capacitors, resulting in a reduced footprint. The asymmetrical module voltages are generated by the multi-winding …

Power Architectures and Design for Next Generation Microprocessors
… architectures for 48V VRM solutions. Two-stage conversions can help solve the design challenges for 48V VRMs. A first-stage unregulated converter is used to step-down the 48V to a specific intermediate bus voltage. This voltage will feed a multi-phase buck converter that powers the CPU. An …
