Manual adjustment? No

Constant Current? No

Dynamic duty cycle/frequency control based external sensor input or OBD data from the computer? Yes




That depends on what you are trying to...

There is no benefit from dynamically controlling the frequency (as far as I can tell) and I'm not a believer of this "magic resonance" that some speak of, but there is plenty of benefit from...

I use 3 of the FQP30N06L MOSFETS in parallel at the moment with the unit I have installed and have tested up to 20 amps @ 14.5VDC with little to no heat using a small 45mm cubed heat sink and same...

Here is where I will explain the how: http://www.hhoforums.com/entry.php?5-Recreate-the-Arduino-Powered-PWM
