Abstract

A modulator designed as a power supply for a microwave magnetron with an output peak power of 3 MW and mean power of 10 kW is described. The 100 transistors used in the modulator are connected in parallel, and their capacitors are switched to the primary winding of a pulse transformer. Across the secondary winding, pulses are generated with a peak voltage of 50 kV, a current of 100 A, a duration of 0.6–6 μs, and a repetition frequency of up to 2 kHz.
