Abstract :
IGBT/SOS-based solid-state generator with 100-kHz pulse repetition frequency in burst mode of operation has been developed and experimentally studied. Ultra-fast IGBT transistors switch the primary capacitive store, and energy is transferred to the pumping capacitor via the pulsed transformer in about 1.5 μs. Current of this process passes via the SOS and insures its forward pumping. After the pulsed transformer ferrite core saturation the reverse current reaches its maximum value of 200–300 A in about 200 ns. At this instant the SOS cuts off the current in about 5 ns that leads to output pulse formation across external load.
