Alternating current generator with permanent magnetic exciter supplying DC voltage via rectifier, reduces capacity of intermediate circuit storage capacitor and reduces ripple of DC current supplied by generator

摘要

An intermediate circuit fed by a high voltage winding (3) of an AC generator, with a storage capacitor (11), supplies DC voltage for a capacitor (16) in series with a choke (15), and a free-wheeling diode (14), via a voltage controller (13) in a time interval when the voltage across a low voltage coil (2) is less than the line voltage. A switch (10) of the intermediate circuit, and a switch (7) with a controller (6) regulate the current supply.
