This paper mainly discusses the design of PWM(pulse width modulation)control scheme of relay and sole-noid valve.Based on the working principle of relay and solenoid valve and the basic concept of PWM control technology,a control scheme of relay and solenoid valve under PWM control is proposed.This scheme has the advantages of improv-ing the control precision of the system,reducing the energy consumption,reducing the heating of the relay and solenoid valve,and extending the service life of the relay,solenoid valve and power supply system.This paper will be elaborated from the aspects of theoretical analysis,scheme design,experimental verification and so on.
