Abstract: FIELD: acceleration equipment engineering, possible use for generating high voltage impulses, generating electronic or ionic beams of microsecond duration with high repetition frequency. 
     SUBSTANCE: generator of high voltage linearly increasing impulses contains a high voltage impulse transformer in form of a set of ferromagnetic inducers, circled by magnetization coils. On both sides of inducers, clamps of magnetization coils are electrically combined and connected to clamps of last compression links of two or more magnetic impulse generators, installed in parallel. Magnetic impulse generators represent a series of at least two compression links, consisting of capacitors and saturation throttles. Generation of high voltage output impulse of microsecond duration is realized due to serial discharge of capacitors of last compression links of magnetic impulse generators through windings of saturation throttles onto the primary winding of high voltage impulse transformer. Impulse feeding delay from various magnetic impulse generators is achieved by selection of interlinking values of saturation throttles of last compression links. To create a linearly increasing impulse of output voltage, capacities of capacitors of last compression links of magnetic impulse generators are compliant with expression: C 1N <kC 2N <...<kC mN , where k=1,1-2 and following condition is fulfilled: C 1N ·L 1N ≈ C 2N ·L 2N ≈...≈C mN ·L mN , where C 1N , C 2N ,..., C mN  - capacities of capacitors of last compression links of magnetic impulse generators, L 1N , L 2N ,..., L mN  - inductances of windings of saturation throttles of last compression links of magnetic impulse generators.
