Title: Induction-Type Electricity Meters
IPC: G01R11/40
Filed: 1966-09-23
Abstract: 1,153,044. Electricity meters. SIEMENS - SCHUCKERTWERKE A.G. Sept. 23, 1966 [Sept. 29, 1965; Sept.30, 1965], No.42697/66. Heading G1Q. In a three phase induction motor meter, three driving systems are disposed at 100 degrees-100 degrees-160 degrees spacing about the axis of a slotted rotor disc, and one of the two driving systems between which the spacing is 160 degrees is connected with reversed polarity. Fig.9 shows the arrangement proposed: the larger circles represent voltage poles, the smaller circles current poles and the + and - signs indicate relative polarity. The slotting (not shown) of the rotor disc may take the form of radial cuts or a circumferential groove, the former arrangement being preferred. The object of the invention is to minimize errors due to stray couplings (represented by the straight arrows in Fig.9) between the driving systems of adjacent phases, and to maintain acceptable limits of error irrespective of whether the phase sequence is normal (I-II II) or interchanged (I-III-II) and of whether the current load is heavy or light or symmetrically or assymetrically distributed between phases. These errors may be further reduced by the expedient Figs.17 and 18 (not shown) of connecting the voltage coils of the three phases in a star and providing a compensating winding which is magnetically linked to the voltage coil of the reversed-polarity driving system but is electrically connected between the star point of the three voltage windings and the fourth wire of a three phase four-wire energizing circuit.

Title: Series connected controlled rectifiers
IPC: H02M1/088
Filed: 1963-10-30
Abstract: 989,325. Electric converting systems; electric supply &c. INTERNATIONAL RECTIFIER CORPORATION. Oct. 30, 1963 [Nov. 5, 1962], No. 42796/63. Headings H2F and H2H. [Also in Divisions H1 and H3] In a circuit comprising a number of controlled semi-conductor rectifiers connected in series each shunted by a voltage equalizing resistance and capacitance, firing of the rectifiers is effected by applying to each gate electrode a current-pulse at least a hundred times the minimum required to fire the rectifier and shorter than the turn on time. In Fig. 1 a pulse is applied to each gate-electrode (via the common primary winding 74) having a magnitude of about 400 times the typical value and of a duration less than a tenth of the turn or time. It is explained that sufficient charge carriers are injected to cause turn-on to be completed and that the initial anode-cathode current is derived from the corresponding one of the equalizing capacitors 32-41. Accordingly, all will be turned on together. Zener diodes 63-69 protect the gate circuits against over-voltage. In Fig. 2, the equalizing capacitors are connected in series with low-inductance pulse transformers having saturable cores. The firing pulses are applied through capacitors 112 and 113 to two groups of series connections of the capacitors and windings, the circuit being thus balanced so the pulses do not reach the supply lines and spurious pulses on the line do not effect triggering. When the circuit is used in an inverter the pulse transformers may be omitted and the firing pulse applied across the series chain of equalizing capacitors and the Zener diodes (Fig. 7). Small chokes 170, 171 may be provided to exclude the pulses from the external circuit and to prevent surges on the external circuit reaching the firing circuit. Fig. 7 also shows a firing pulse generator in which, when a pulse is applied to the gate electrode of controlled rectifier 184 a capacitor C s  discharges through a pulse transformer PT and a biased saturable reactor SR. The latter saturates after a delay sufficient to allow the controlled rectifier to become fully conductive so that a very steep pulse edge is achieved. The saturation current is less than the magnetizing current required in winding 174 before transformer action can occur. The circuit may be constructed from modules comprising a base member supporting a semiconductor rectifier 121 a Zener diode a resistor and a capacitor or supporting in addition a saturable core pulse transformer (Figs. 3 and 6, not shown). The modules may be connected in sub-groups (Fig. 4, not shown, and Fig. 7) which may be arranged in groups (Fig. 5, not shown), the transformers in some sub-groups being connected in reverse polarity.
