Title:
DEVICE FOR TRANSMISSION OF INFORMATION THROUGH A THREE-PHASE POWER LINE
Document Type and Number:
WIPO Patent Application WO/1990/006639
Kind Code:
A1
Abstract:
The device comprises a receiving (1) and a transmitting (2) unit, the latter being provided with a switch (7) with an element (8) for controlling the duration of its closed state, and a unit (9) for determining non-full-phase regime. The receiving unit (1) comprises a circuit (10) for filtering symmetric components and a narrow-band filtering circuit (11). The first outputs of coils (41, 42, 43) are connected to the corresponding inputs of the transmitting unit (2), whereas the second outputs are connected to the anodes of the first diodes (51, 52, 53), the cathode of each of which is connected to the first input of the switch (7), the second input of which is connected to the anodes of the second diodes (61, 62, 63), the cathode of each of which is electrically connected to the corresponding input of the transmitting unit (2).
