Title: Antiparallel single phase rectifier DC motor drive - has current and smoothing choke coils wound on common shank to improve current limiting and commutating action
Inventor: NICOLTSIOS GRAMMENOS DIPL ING
IPC: H02M7/162
Filed: 1976-07-29
Abstract: The application is principally related to DC motor drives supplied from anti-parallel connected controlled rectifiers. These have two current circuits: one through the armature (L) of the motor and the other a current circuit between the two rectifiers (S1, S2). Commutation and current limiting action of chokes is improved and space reduced by winding the choke coils (W1-W6) on the limbs of a three limb iron core. The windings are placed in pairs, each pair on one limb. Thus the smoothing choke coils (W2, W5) are on the centre limb and the limiting chokes (W1, W4; W3, W6) on the two outer limbs respectively. The design is partic. suited to single phase applications and esp. traction motor drives.

Title: Peak load controller for max demand meters - uses exponential moving average to calculate actual average power consumption
Inventor: KUSCHE PETER DIPL ING
IPC: G01R21/133
Filed: 1977-05-09
Abstract: The peak lead controller comprises a maximum demand meter (MZ) set to 100% of the permissible consumer load. A number of parallel lines carry the respective instantaneous values to an arithmetic unit (20) which calculates the max. permissible load variations with time. A further signal (B) which is the difference between the measured instantaneous value and the exponential moving average of the power, is transmitted via parallel lines together with the output of the arithmetic unit, to a divider (21). The output signal from the divider is fed to a control unit (22) to operate load isolating relays. For serial transmission, the max. demand meter has a frequency comparator (23) which compares the pulse rate, proportional to the instantaneous power, with a reference frequency (FR). Logic signals are fed to the control circuit (24) for switching the lead relay in and out. These signals depend on whether or not the instantaneous power is greater or less than the moving instantaneous maximum (AM).
