Towards lossless electrical energy converters
Electrical energy is typically converted four times between source and load, by over 100.000 GW installed converters. Over 99% efficiency is already reality, e.g., in PV inverters, however in a trade-off with power-density and complexity. Thus, most converters stay below the technical performance limits. Incremental advances in semiconductor technology will continuously push these limits’ values, but does not fundamentally change it. This project takes a disruptive approach, investigating partial-power-processing (PPP): Recently, we operated a 99%-efficient 2-level half-bridge in a multilevel topology, increasing the external capacitive-load charging voltage and power 6-times, while keeping…
