This document presents a new Multilevel Energy Buffer and Voltage Modulator (MEB) design for micro-inverters. The MEB helps reduce the range of voltage conversion ratios that the DC-AC converter portion of micro-inverters must operate over. It does this by actively stepping the micro-inverter's effective input voltage in sync with the line voltage variations. This allows the MEB to partially replace bulk input capacitors while reducing the total size of twice-line-frequency energy buffering capacitance needed. A prototype micro-inverter incorporating an MEB was built and tested, demonstrating that the MEB can enhance performance by improving efficiency and reducing energy buffering needs.
