The present manuscripts discusses the development of a forty stage, 22 kV solid-state pulser based on Linear Transformer Driver (LTD) topology employing 240 MOSFET switches operating at rep-rate of 1 kHz. A transformer based triggering scheme is implemented which enables the switches to operate at a jitter of < 5 ns. Each stage drives ∼ 220 A peak pulsed current and the output voltage of forty such stages are inductively added to generate 22 kV across 100 Ω resistive load, having a rise time of ∼ 20 ns. The paper presents the developmental steps, highlighting the temporal jitter characteristics ∼ 5 ns (peak to peak jitter measured at output voltage at load end) demonstrated by the system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
