Hi,
I am giving controllers PWM to the IPM Power modules.
My controller pwm will be 8 KHZ now i want to add an filter which can passes frequency upto 10KHZ
When i was calculating value of RC
FL=1/(2*PI*R*C)
FL=10KHZ
Now the two components are unknown here..
Are R or C Takes randomly or are there any criteria to select the Proper R and C...
I assumed C=10nF (assuming is ok or not) and i got R value=1.59K
is this right approch..??
