昇圧チョッパ回路を用いた無拘束ポペット弁の駆動回路

抄録

This paper presents a driver for unconstrained poppet valves based on a step-up chopper circuit. Unconstrained poppet valves are small-sized and lightweight, capable of controlling air flow around 0.5MPa up to 10L/min. Drivers for unconstrained poppet valves require generation of pulse signals and amplification of driving current. We applied a step-up chopper circuit to realize these requirements on a driver. We found that the developed chopper-based driver could control unconstrained poppet valves.
