Hello All,
So I have created so far a boost converter which is driven by my arduino's pwm. Without drawing up a schematic of what I've done as I'm sure you're all knowledgeable enough to understand what I must have done, I am trying to keep a steady output voltage when various loads are attached.
I am using a single cell 3.7-4.2v 18650 type of battery, a mosfet two capacitors, a shottky diode and have tried a wide range of inductors from 0.06uH to 0.110uH. I can get a lot of volts out this thing but the voltage is always reduced to almost nothing when I attach a load.
I am attempting to power a small heating element. These elements range in ohms from 0.02 up to 1.8. My ideal output voltage would be 5V and I would like 10 amps. I cant figure out whether I need to do some type of load isolation, need more boost or what.
While this isn't my first electronics project I am still pretty new to all of this and would really appreciate some help.
Thank You, John
P.S. I say buck and boost because I want the power out to be adjustable from 3 to 5 volts. As previously stated - I am triggering the mosfet via arduino pwm..
