The contribution proposes a novel method for reduction of voltage drop across Darlington circuits when used as power switches and reports preliminary experimental results. The compensation leads to at least an effective doubling of the energy efficiency of the switch while no detrimental effects on current fall time have been found. The scheme is easily realisable in modern electronic technology.
