Claims

20 pulses containing a bridge, in each of which are connected in series the COP.CHISINES coil inductance and peak} p and in series diodes Ki4i.i.-ii ... 3 torr, a storage capacitor is included in one bridge diagonal - two parallel circuits, one of which consists of a series-connected power source and throttle, and the second one of a series-connected capacitor and load, a series-connected diode and a capacitor in each arm of the bridge are connected in parallel to the thyristor, with the diode and the shooting range History included counter. The drawing shows the principal electrical circuit of the proposed generator. The generator contains thyristors 1-4, diodes 5-8, inductor coils 9-12, storage capacitor 13, capacitors 14-18, load 19, choke 20, power supply 21, and control unit 22. The generator works as follows. From the moment of arrival from the control unit 22 of the pulses to the control electrodes of thyristors 1-4, an oscillatory charge of the capacitor 13 occurs on the circuit: the upper face of the capacitor 18, coil 9, thyristor 1, capacitor 13, thyristor 4, katuiza 12, load 19, lower capacitor plate 18. At the time of changing the direction of the current, the thyristors 1 and 4 are turned off and the current continues to flow through diodes 5 and 8 and capacitors 14 and 17. At the same time, the sensing sensor 13 discharges along the circuit of the left capacitor plate 13, diode 5, capacitor 14, katuizha 9, capacitor 18, load; and 19, coil 12, diode 8, capacitor 17, the right side of the capacitor 13. During the discharge of capacitor 13, capacitor 14 and 17 are charged and at the moment when the potential on them becomes higher than the potential at capacitor 13, diodes 5 and 8 are locked, and tori i and 4 apply a reverse voltage, which contributes to the restoration of their spectral strength, when: the pump stops the discharge of energy through diodes 5 and 8 in all load modes. From the moment the thyristors 2 and 3 are turned on, the process of charging the capacitor 13 is repeated. Each pair of thyristors 1, 4 and 2, 3 forms one period of high-frequency electrical oscillations in the load 19. The presence of capacitors 14, 17 and 15, 16 contributes to the locking of the diodes 5-8 during the switching period, while the power delivered to the load is compared with the known more than doubled.
