Abstract

PURPOSE: To reduce the weight of a titled device without decreasing transmission electric power by rectifying the Ac of commercial frequencies, converting it to the AC of high frequencies by means of switching circuits, and obtaining rated outputs through plural transformers.
CONSTITUTION: The commercial 3 phase AC from a power receiving terminal 1 is rectified in a rectifier circuit 2 and is energized respectively simultaneously without overlapping by means of power switching transistors 3aW3d. This AC voltage is applied to the primary windings of insulating transformers 4a, 4b. It is for the purpose of making this device manufacturable in terms of the number of turns of the secondary sides to use the plural transformers 4a, 4b. Since the AC to be applied to these primary windings is of frequencies higher than commerical frequencies, the weights of the transformers 4a, 4b are reduced. The outputs of the respective insulating transformers are combined, whereby the rated output is obtained.
