I am using Series SVP Proportioning Solenoid Valve from
https://www.electro-tech-online.com/custompdfs/2008/08/SVP_iom-1.pdf
In the pdf they have not mentioned any information regarding the inductance & switching frequency
Hay
I have tested proportional solenoid with TIP122 & 1KHz frequency
Across the load I am getting sufficient voltage but I am not getting the sufficient current to the solenoid
So now I have to use power MOSFET (IRL540) & frequency above 20kHz
How to interface LPC2106 with MOSFET (IRL540)
please provide me information information

Thanks for the reply
The proportional valve require unidirectional PWM pulses
By varying the PWM duty cycle I have to control the valve position

I don't see how.IMO the inductance of the solenoid winding is having an effect upon the solenoid current at those higher frequencies.
XL = 2 * Π * L * f
I don't see how.
Providing the current is never allowed to decay to zero, the average current flow will be deturmined only by the duty cycle, the resistance and diode loss, regardless of the value of the inductor or the frequency. A larger inductance or higher frequency will just smooth the current ripple out more which is a good thing.
