摘　　要：分析了影响高速电磁开关阀开启和关闭特性的电气因素,设计了一种PWM调压的高速电磁开关阀双电压驱动器,构建了高速电磁开关阀动态特性试验平台,验证了该驱动器改善高速电磁开关阀动态特性的有效性。The electrical factors affecting on/off properties of high-speed switching solenoid valves were analyzed. A dual voltage driver of high-speed switching solenoid valve controlled by PWM was designed. A high-speed switching solenoid valves dynamic test stand was established. The effectiveness of improving the dynamic characteristics of the dual voltage driver of high-speed switching so- lenoid valve controlled by PWM was validated by test.
