Tonfrequenz-Rundsteuersender mit einem kapazitiven Speicher aufweisenden Pulsstromrichter

摘要

The invention pertains to an audio frequency ripple control transmitter including a pulsed A.C. rectifier fitted with a capacitive accumulator (2). The transmitter (2) has a LC coupling device for oscillatory circuits (12), whereas the pulsed A.C, rectifier (4) is provided with a capacitive accumulator (6) and an adjustment and control device (10) comprising an adjustment unit (16) and a pulse-width modulator (18), at the outputs of which control signals (S1......, S6) from the pulsed A.C. rectifier (4) wait for processing. Said adjustment unit (16) is comprised of a ripple control regulator (22) and an A. C. regulator (24) which are connected at the output by a summing point (28) linked at the output to the pulse-width modulator (18). The resulting audio frequency ripple control transmitter (2) is cost-optimal and its investment and commissioning cost is clearly lower in comparison with a conventional audio frequency ripple control transmitter.
