High-speed solenoid valve is the core control element of digital flow technology, and its dynamic response and effective duty cycle range seriously affect the flow control accuracy of the system. To further expand the effective duty cycle range, a phase-shifted pulse width modulation (PWM) voltage drive strategy including reference PWM, pre-excitation PWM, excitation PWM, high-frequency PWM, pre-unloading PWM, and unloading PWM was proposed in this paper. Firstly, the working principle of the phase-shifted PWM voltage drive strategy was given, and the theoretical model of dynamic characteristics of high-speed solenoid valves was established. The simulation analysis and experimental verification of pre-excitation PWM and pre-unloading PWM duty cycle were carried out. The results show that compared with the composite PWM voltage drive strategy, the opening and closing pressure response time of the valve core are reduced by 87% and 37.9%, respectively. When the operating frequency is 100 Hz, the controllable duty cycle of the normal opening and closing of the valve core is extended from 28.5%–77% to 8.5%–81%.
