Abstract

This paper studies extremely high-precision efficiency measurement by building a back-to-back (BTB) system with a high-power DC-DC converter in order to realize a 100kW high efficiency energy conversion system (HEECS) chopper with 99.5% efficiency. The newly proposed water-cooled 2-phase HEECS BTB chopper system achieves a reduction in input power and enables highly precise measurement of a high-power DC-DC converter with an extremely high efficiency of 99.5%.
