If the load get to high, I would shut the ouput down. An incorrect snubber will simply make it worse. Shall follow with interest. Last edited by rcheshire; at So much simpler than dealing with low-value shunt resistors.

I am sure there are plenty of development platforms out there that are just as good though, but i have too many including Beaglebone Fett and other smaller stuff. Originally Posted by Squibcakes. Power dissipation is critical as I was targeting a SOT package. That is good stuff. This part is available from both Mouser and Digikey I believe. Warnbro, Western Australia Posts: Page 2 of 5. Cheers Garbz for the heads up on the dew point calc.
Up to 30A in an SO-8 package. The All Things to All People controller. The load can be between 0 and 20 amps. So the best platforms are high speed 32 bit processors now.
Have attached piccies of a unit i made up for fun that could a Have one DewHeater channel controlled via several means including using dewpoint, defined PWM duty cycle or auto temp delta mode. The humidity sensor is on the inside lid of the small box that sits on the tube, and has holes in the lid to pick up the dew. To get that kind of noise you need some kind of reactance capacitance or inductance either from components, cables, or even the MOSFET itself.
Find all posts by mswhin I need to get to the bottom of pwm frequency — resolution seems self explanatory. Originally Posted by Garbz A double is still a float, just a double precision float is 64bits long instead of 32bits.
Each channel is unique, as for my setup I have a guide scope as well, so tweaking can be done seperately on each channel. Powered by vBulletin Version 3. Although I have seen some of these covered with heatshrink. A correct snubber can help. Datasheet pdf. Equivalent Simply adding 2 doubles takes around instructions. Your posts are an education. Shall follow with interest. Very nice project Chris.

Another really really cool platform is the PSoc4 platform which as a brilliant IDE that is component based and I believe super easy to develop. Exactly what I learnt in my last lesson in Micros lecture only last week. The strategy is to estimate the pwm value linearly for setpoint temperature and dither either side to maintain temperature. I figure this will permit a wide range of customisation. Find all posts by wasyoungonce. Related Posts
