FIELD: electrical engineering. SUBSTANCE: power supply has synchronous generator with rectifier in armature winding circuit; connected to rectifier DC buses are generator voltage measuring device and voltage regulator whose output is connected to field winding. Generator field winding is designed for operation at voltage lower than rated rectified phase value by phase forcing factor; transistor voltage regulator is provided with current limiting device that functions to limit field current at voltages across generator phase leads lower than rated value. EFFECT: improved overload capacity in starting squirrel-cage induction motors of comparable rating. 1 dwg
