【Abstract】 This paper deals with the static characteristics of high-speed on-off valvescontrolled by analog pulse width modulators.The analog pulse width modulator with naturalsampling and bi-edge modulating is analysed.From the point of views of physical conceptionand engineering application,the influences of the valve’s changeover time on both its staticcharacteristics and the carrier frequency are discussed.更多还原
