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