Title: Tuning of oscillating circuits in closed filter circuit - compares outputs of equal amplitude inputs equally and narrowly spaced about resonant frequency
Inventor: LOEPER JOACHIM ING GRAD
IPC: H03H3/00
Filed: 1975-10-08

Patent DE-2643645-A1 (DE)
Inventor: LINDEN WILHELM DIPL ING
IPC: G05F1/44
Filed: 1976-09-28
Abstract: The control device for the valve control pulses (p1 to p6) of the line-commutated converter has an ancillary device (2) for balancing the control pulses. The ancillary device (2) contains two series-connected delay stages (18, 24), of which the first (18) is fed with a pulse chain formed from the sum signal (a) of the control pulses (p1, ..., p6). The second delay stage (24) transmits a pulse chain as an ancillary control voltage (UZ) to which a pre-defined control voltage (UC) is added in an adder (8) for the valve control voltage (US). In the second delay stage (24), a control circuit (30, 50) is activated which ensures phase coincidence of the sum signal (a) with the ancillary control voltage (UZ). The control device enables a high degree of balance of the control pulses regardless of the tolerances of the components which are to be used. <IMAGE>

Inventor: LENGENFELDER WALTER ING GRAD
IPC: G01R27/20
Filed: 1976-11-26
Abstract: To be able to read the earthing resistance of an earth electrode (1) directly without calibration and without verification, a constant-current source (6) is connected to the earth electrode (1) and to an auxiliary earth electrode (2), which supplies an alternating current of constant magnitude and defined frequency. A high-impedance measuring probe (7) picks up the feed voltage dropped across the earth electrode (1), which is amplified in an amplifier (9), filtered in a filter (14) and rectified at a rate of the frequency of the measuring current in a rectifier (10). The output signal of the rectifier is integrated by an integrating section (15) and indicated by an indicating instrument (12). Influences of various mains frequencies and their harmonics can be virtually eliminated by a suitable choice of the frequency of the measuring current. <IMAGE>
