Background technology:
Pulse transformer is a device commonly used in the electronic circuit, be mainly used in impedance matching, rising or reduce pulse voltage, change in pulse deformity, isolation, the coupled and other electronic circuits, pulse characteristic when output voltage reaches certain value, can't continue raise pulse voltage owing to the restriction of insulation system, insulation, electromagnetic material based on unipolarity, therefore, the output pulse power of separate unit pulse transformer is less, and voltage is lower, can not produce large power high voltage pulse.
At present, the method that is used to produce large power high voltage pulse mainly is to adopt the nomotron of high-power to realize, the high-voltage DC power supply of modulation is carried out switch control, and obtain higher pulse voltage.Owing to be subjected to effects limit such as electron tube is withstand voltage, volume, heat radiation, voltage pulse output and its circuit complexity, involves great expense only about 10KV, be very limited in the practical application, that is to say that producing high-voltage pulse is difficult for realizing, therefore, has restricted the high-voltage pulse technology application.
The utility model content:
The utility model provides a kind of generation device of pulse transformer---and tandem formula high voltage pulse transformer has solved existing generation large power high voltage pulse apparatus structure complexity, involved great expense and has been difficult for the problem that realizes.
Technical solution of the present utility model is with many pulse transformers being connected in series by winding, constitute a pulse transformer assembly, output voltage pass through one-level, secondary ... n and being formed by stacking, with the action of low-voltage pulse power source transition of modulation is high-voltage pulse, thereby obtains very high pulse voltage output.
This device is made of by the balance windings in series the winding of many pulse transformers, wherein, first order transformer is provided with elementary winding and secondary high pressure winding, stage transformers is provided with excitation winding and secondary high pressure winding later on, the balance winding is connected with the secondary high pressure windings in series of previous stage transformer respectively, be connected in parallel with the excitation winding of back one-level transformer, the high pressure winding of back one-level transformer just induces high-voltage pulse by the balance winding, and load is connected across between the common port of back level transformer secondary output high pressure winding and prime primary winding.By the Voltage Series addition that prime transformer and back level transformer high-voltage winding induce, just obtain both high-voltage pulse sums, produce large power high voltage pulse.
Good effect of the present utility model is: utilize electromagnetic induction principle, replace the high voltage switch electron tube to produce large power high voltage pulse by transformer, can obtain higher output high-voltage pulse, generally can reach 60KV～100KV, pulse duration is 1～10vus, simple in structure, dependable performance, can be applicable to and set up impulse electric field and directly loading operation, voltage adjusting range and frequency range that broad is arranged, widened the scope of application of pulse transformer, high-voltage pulse technology is applied in field widely.
