SHIPBOARD POWER GENERATOR WITH HIGH ROTATION FREQUENCY INTENDED MAINLY FOR SHIPBOARD POWER PLANTS Russian patent published in 2012 - IPC H02M5/27 

FIELD: electricity.

SUBSTANCE: introduced into the shipboard power generator are a second three-phase synchronous generator with the number of pole pairs equal to p±1, two three-phase summing transformers, three low capacity diode bridge rectifiers, three pulse drivers, six control pulse drivers and three triggers. The three-phase windings of the both three-phase synchronous generators are connected to the corresponding primary windings of the three-phase summing transformers having their secondary windings in-parallel. The ends of the secondary windings of the phases of the corresponding branches of the first three-phase summing transformer are interconnected; the ends of the secondary windings of the second three-phase summing transformer are connected to the beginnings of the secondary windings of the first three-phase summing transformer phases; in the first branch Phase A of the first three-phase summing transformer is connected to Phase A of the second three-phase summing transformer, Phase B is connected to Phase B and Phase C - to Phase C accordingly; in the second parallel branch of the secondary windings serial connection is performed with one phase shift. The beginnings of the secondary windings of the first three-phase summing transformer are connected to the three low capacity diode bridge rectifiers and to the three groups of anti-parallel rectifiers of the bridge thyristor frequency transformer with immediate connection.

EFFECT: voltage distortion coefficient reduction without filters application.
