The invention relates to a pulse

technology and can be used in radio transmission devices for various purposes.

The purpose of the invention is to improve reliability with increasing interval of saturation delay of the core of the saturation throttle.

The drawing shows a circuit diagram of a magnetic pulse generator.

The magnetic pulse generator contains a power source 1, a storage capacitor 2, a key element 3, a discharge choke 4, a pulse transformer 5, a capacitor 6, a saturation throttle 7, a load 8, a source of control pulses 9, a pulse amplifier 10, a current transformer 11, a driver

12 pulses, logical element OR

13 and the charge unit 14, which includes the charging diode 15 and the charging choke 16.

The positive pole of the power source 1 through a serially connected diode 15 and the choke 16 is connected to the first terminal of the capacitor 2 and the anode of the key element 3, the cathode of which is connected through the serially connected choke 4 and the primary winding of the pulse transformer 5 to the negative pole of the power source 1 . Parallel to the capacitor 6, the secondary winding of the pulse transformer 5 and the serially connected saturation inductor 7 and the load 8 are connected. The load transformer 8 has a current transformer 11, the output of which is connected through the first input of the logic element OR 13 to the the second input of the logical element OR 13, the output of which through the amplifier 10 pulses is connected to the input of the key element 3.

Magnetic pulse generator works as follows.

The pulse coming from the output of the source 9 of the control pulses passes through the logic element OR 13, is amplified further by the amplifier 10 pulses and is fed to the input of the key element 3. The latter closes and the discharge is pre-charged through the charging diode 15 and the charging choke 16 from the storage power source 1 the capacitor 2 through the key element 3 and the bit choke 4 on the primary winding of the pulse transformer 5. On

The secondary winding of this transformer appears voltage and the capacitor 6 begins to charge. Under the action of a voltage that builds up on the capacitor 6, the core of the choke 7 is saturated, resulting in a rapid discharge of the capacitor 6 through the saturated choke 7 to the load 8, on which the output pulse is formed. After the end of the output pulse, the capacitor 6 is charged in reverse polarity, and its charge is transmitted back to the capacitor 2 through the pulse transformer 5 and the key element 3. Thus, the second current pulse flows through the key element 3 at the end of the operating cycle.

To ensure the sustained switching on of the key element 3, at any time interval between the current pulses, a second control pulse is formed in the device on the key element 3. This pulse is formed as follows. With the passage of a current pulse through the load 8, a pulse appears at the output of the current transformer 11. This pulse triggers the pulse shaper 12, which generates a square pulse arriving through the OR 13 gate and amplifier 10 pulses at the input of the key element 3. The latter closes and thus is prepared for the passage of the second current pulse.
