FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to electric power generation systems with adjusted frequency and voltage at constant RPM. Device for producing voltage of adjustable frequency at output of multiphase AC generator with constant shaft rotation frequency includes three synchronous AC generators, combined with common drive, main stator three-phase windings thereof are connected in three branches so that in each branch three opposite phase windings are connected in series, while origins of branches form three-phase power output with controlled frequency voltage, and ends of branches are Y (star) connected.
EFFECT: technical result consists in reduction of weight and overall dimensions, higher reliability.
