FREQUENCY CONVERTER FOR HIGH-SPEED GENERATORS

摘要

The invention relates to a method and a device for adapting the alternating current produced by a generator (1) or the alternating current produced by a generator (1) and supplied to a network (8), said generator (1) having at least one field coil (2). To achieve a flexible adaptation of the power that is supplied to the network (8) with low switching losses, a static frequency converter (9) is used to adapt the current between the generator (1) and the network (8). Means (3) are also provided to control the power that is supplied to the network (8), said means regulating the intensity of the excitation field that is produced by the field coil(s) (2) and the phasing between the frequency converter voltage and the generator voltage or network voltage is appropriately controlled.
