    Digtal ports replacing ADC

    Thanks for your valuable inputs. But it is my mistake I did nt give the complete details. actually It is a very big project,all the ADCs in the uC were used .now no ADC left for the present requirement.Now I have left only choice to use digital ports in uC.It is not possible to change the uC...

    pwm inverter filter inductor design

    Hi goldsmith, My inverter output power rating is 300W,120 Vpk,5 Apk,30Hz pure sine wave. presently our load is 10 ohm,8mH,which is variable. Presently we dont have feedback,it includes in future planning. I heard closed loop of inverter is somehow difficult ,please provide the good stuff for...

    difference between inrush current and over current

    I want to sense the inrush current and as well as over current ,i want to protect my circuit from more than rated current.if i use a current sensor and protect my circuit,circuit will be tripped during inrush also,which is not my requirement.I should not use NTC also because i want to moniter...

    What is the voltage across r39,r40?

    can you explain little bit more clearly.if we increase the current how voltage will be effected
  15. R

    What is the voltage across r39,r40?

    The voltage across the r39, r40 should be 0 to 28v pulse with 2usec pulse width,but is 28v to 28.4v pulse with 2usec pulse.if we think when the switches are off the total voltage will be present across those resistors,but it is not showing in simulation.if we start the pulses then only i am...
