It was announced on April 2, 1941. No. 42287 (305695) to the People's Commissariat of the Electrical Industry of the USSR

The main author. St. No. 60954 of March 3, 1942 on the same person

In the main auth. St. No. 60954 describes a device for the phase control of grids of ion devices consisting of a supply transformer, an ohmic resistance, saturation droplets and a pulse transformer; the latter is equipped with a biasing winding connected in series with the bias winding of saturation throttles in order to extend the range of regulation.

The device is a development of the invention according to the main copyright certificate. In order to reduce the overall dimensions of the apparatus, it is proposed to parallel the primary winding (or windings) of a pulse transformer with its three-phase execution to connect capacitors tuned to resonance with the inductance of the transformer. In order to obtain an approximate constancy of the peak shape over the entire control range, the secondary phase windings of the feeding transformer are taken (with a three-phase implementation) for slightly different numbers of turns.

FIG. The circuit diagram of the device is presented; in fig. 2 is a diagram of the throttle saturation in the device.

A device for controlling three- and six-phase ion rectifier grids (a phase shifter) consists of a three-phase transformer 1, ohmic resistances 2, saturation throttles 3 and pulse transformers 4 (the secondary windings of which are not shown in the diagram; with biasing windings 5 and 6, respectively, connected The phase shifter is three-phase and parallel to the primary winding of the transformers 4 are capacitors 7 connected to the current resonance with inductance pulsed transformers, due to which the size of the device is reduced.

ION DEVICES

№62133-2 The secondary windings of each phase of the transformer / have unequal and appropriately selected voltages, due to which the own power consumption of the pulse transformers is completely compensated, and the voltage at the terminals of the pulse transformer does not change with the control bias current, according to which the amplitude and shape Peaks are not impaired over the entire control range.

Throttle i saturation. 3 also has a three-phase implementation (FIG. 2) with a common core, pass-through windings of an alternating current and a biasing windings 5 of direct current. In order to compensate for the electromotive force from the unbalanced high harmonic alternating current amperages induced in the biasing winding of the direct current, two such chokes can be used in series or parallel, similarly to the well-known single-phase circuits.

The saturation choke can be provided with a second special biasing winding fed by unregulated direct current. Power, in particular, can be taken from the primary winding of the transformer / through a cuprope rectifier connected in a bridge. The specified current output is intended for a constant voltage phase shift on the primary winding of the pulse transformer relative to the secondary voltage of the transformer / at an angle of about 90 °. Due to this, firstly, a correspondence is established between the sign and magnitude of the control current of the first main magnetizing winding and the rectifier rectified voltage, and, secondly, the power consumed by the phaser for control, which is especially important for autoregulation purposes.
