Description

An arrangement is proposed for generating saw-tooths, eg, Kei-uiii, in which discharge K01 of the centrifugal generator is applied to the anode circuit of an auxiliary high-frequency generator with 1 inductive coupling (block-generator). excited by a certain value; accumulate on a suspended capacitor.

In existing generators of a sawtooth nanrgein of the specified type, the charge is 1 ton; c; -1to e. csto; 1 (): about C1M1; ni: 10-type voltage, is usually placed in a circuit of the generator-tube, and the niloobraznaya form voltage: is induced by a hypothesis | Density: a capacitor and its fast discharge through the generator.

In the proposed ycTpoiicTBe, the capacitor in the grid is charged and the generator lamp and the pilot voltage of the saw voltage across the generator are reversed: the capacitor is quickly charged with the voltage; M arises in the grid circuit when the generator is excited, and then slowly discharges through the load resistance. In conjunction with zti: m in the proposed device for a gpner; 1zap: sawtooth or lr;: And there are unusual ways to turn on the generator and sync.

The drawing shows a diagram of the proposed yiOTnoiicTBa, where: / is a double triode, the left of which is e1I1Crony1. . and rights are generator; 2-high frequency generator transmeporMator:.-Sigitnye D11o: ce. 4-rsgu.t tor: teren: t synchronization; 5-resistance is a voltage regulator of oscillation frequency; 6 - xc-ndensors. Tyuchat.t 4acTOTHiii d ;; apazo wc; 7 output voltage divider.

The proposed device operates due to the discharge of one of the capacitors 6 through the highly intelligent resistor 5 and the fast charge of this capacitor connected to the grid of the right lamp when the auxiliary BbieoKoii frequency generator is excited with: inductive feedback during the reverse of the sawtooth wave. The proposed device for generating relaxation oscillations is synchronized with the aid of a special lamia (in diagram No. 87331-2 -

me left triode). In the ano / dpa circuit of it, which is connected to the chain of the sethi of the high-frequency generator, the current flows only at the moments of the opening of the right triode, i.e. during short periods of time, the kolda ended the straight course of the sawtooth oscillation and its reverse CW | D occurs. The power supply of the clock circuit of the synchronization lamp is made by applying voltage from the capacitor 6 through the secondary circuit: a high-frequency transformer 2 of the auxiliary generator. The grid of the auxiliary you |; - frequency generator 10 directly connect soy | dinep with tap from the specified secondary winding of the transformer 2.

During the direct course of the relaxation oscillation by negative voltage: the capacitor 6 is closed by both luminaires: the nature of the grid circuit, the left-hand side of the anode.
