Abstract :
This paper gives the formula of current in proportional solenoid coil When the PWM control is applied, analyzes the impact of the PWM frequency and duty cycle on current and current fluctuations, and then discusses the question that should be noticed on detecting the current. Finally, the paper describes the emergence of high-frequency interference in output circuit and the inhibition of high -frequency noise.
