SLE 05 The invention relates to electrical engineering and is intended to control the thyratrons of key generators. A control pulse shaper is known that is constructed on the basis of a series inverter and allows controlling a large number of controllable power valves (thyristors, thyratrons) ij. However, the operation of these formers in a wide frequency range is unstable, leading to the through burning of two valves connected in series (tilting of the device). Closest to the proposed invention in its technical essence is a control pulse shaper, containing two series-connected forming circuits, each of which contains series-connected thyris. the torus and the pulse transformer, to one of the poles of the power supply, H11H or to its middle output, connect one output of the storage capacitor, the second output of which is connected to a common point of the forming circuits, the outputs of the pulse transformers are the outputs of the control driver, and the control electrodes of the thyristors its inputs are 2.1. The disadvantages of the circuit is the low reliability, which is manifested in the instability of the circuit to tilting at high Frequencies and the formation of signals only along two lines. The aim of the invention is to increase reliability and enhance functionality. The goal is achieved by the fact that a control pulse shaper containing two series-connected forming circuits, each of which contains a series-connected thyristor and a pulse transformer, is connected to the power supply one output of the storage capacitor g whose second output is connected to a common point of the forming circuits, the outputs are pulsed Transformers are the outputs of a control driver for a pulse and the control. The electrodes of the thyristors are its outputs, equipped with two additional each of the circuits consists of an additional thyristor, a capacitor, and a pulse transformer, each pole of the power supply in a circuit. The leads of one of the additional shaping circuits are connected to the corresponding main shaping circuit, the outputs of which are the leads of the additional capacitor, in parallel with which are connected each other connected additional thyristor and a pulse transformer. Figure 1 presents the diagram of the pulse shaper; Fig. 2 is a graph of a sequence of pulses controlling a driver of a driver. The control pulse shaper contains a shaping circuit 1 consisting of a storage capacitor 2 and a parallel connected circuit from a controlled valve 3 and a primary winding..pulse transformer 4 connected to the positive power source 5. The minus of the power supply 5 is connected to a similar formation circuit 6, consisting of a storage capacitor 7 and a parallel-connected branch from a controlled valve 8 and the primary winding of a switching transformer 9. Between the formation circuits 1 and b, the series-connected circuits 10 and 11, consisting from controlled valves 12 and 13 and the primary windings of pulse transformers 14 and 15. The common coupling of circuits 10 and 11 is connected through a capacitor 16 to the midpoint of the power supply 5, the secondary windings of the pulse transformers tori 4,9,14 and 15 are connected to loads 17-20. The control electrodes of the valves 3, 8, 12, and 13 are connected to the outputs of the control pulse distributor. The control pulse former operates as follows. When the trigger pulse arrives at the control electrode of the controlled valve 12 (Fig. 2, a), the latter is unlocked. The current flowing through it creates a control voltage pulse on the load 18 connected to the secondary circuit of the pulse transformer 14. At the same time, the oscillating charge of the capacitors 2 and 16 occurs. When the current through the controlled valve 12 decreases to zero, it is switched off. The circuit is in a standby state until the next control pulse, the inputs to the input of the control valve 13 (Fig. 2, b), does not open it. In this case, the oscillating charge of the capacitor 7 through the open controlled valve 13 from the charged capacitor 16 begins. Flowing through the primary winding of the pulse transformer 15, this creates a pulse of control voltage on the load 19 connected to the secondary winding of the pulse transformer 15. After the current pulse passes through the control valve 13, it switches off, since the voltage on the capacitors 7 and 16 is reversed for it. The circuit is then in the standby state of the control (pipuls to the inputs of the controlled valves 3: AND 8. The start pulse coming to the control input of the controlled valve 3 (fig.2, c) unlocks the controlled valve 3 and The current flowing through it recharges the capacitor 2. At the output of the transformer 4 forms, the necessary voltage pulse is driven. After the process of recharging the capacitor 2 is completed, the controlled valve 3 is closed, as the voltage on the capacitor 2 becomes negative for it. in schemes After the arrival of the control pulse at the input of the valve 8 (Fig. 2, d), are similar to those discussed above. The sequential inclusion of controlled gates in the power supply circuit favorably distinguishes the control driver from the known former, since the stability of the circuit to tilting increases. wide frequency range due to the fact that four controllable fans with equal pressure control in series are connected in series to the power supply source, which practically excludes the possibility of simultaneous through mountain audio device, and valves, respectively; governmental, short for shkani power source.
