Hi,
I produced a variable dutycyle and variable frequency and output on RB0 (HPWM). thi is driving a mosfet driver.
You can view the circuit here:

the problem I am getting is when I supply current to the coil, (which is probably not 10uH because I used the default one in Orcad, I'll need to calculate if you want. It has 300 feet wire wrapped on a 2 inch diameter PVC and 3 inch long) . the problem is when I put on the 36v actually for now 12v for testing purposes, the output pin from the picchip stops randomly for oscillating ....
I mean 1 second on 0.5 second off etc...
When there is no load the pic keeps oscillating !! why is this
thanks for the help
K
