Device for transferring high-power electric energy from a higher frequency three-phase supply network to a lower frequency single-phase load network

摘要

1. A device for the transmission of electric energy of high power from a three-phase supply network (1) of high frequency into a single-phase load network (3, 4) of low frequency, characterised by a frequency-dividing direct converter (51, 52, 61, 71, 72) which is connected to the supply network (1) and has a threephase output (5, 6, 7), wherein two phase outputs (5, 6) are connected to the load network (3, 4) and also by means of an electronic phase shifter (10, 12) to the third phase output (7) in each case in order to balance the load.
