I'm in the process of building DC power supply that will run off 240vac mains.
The main reason for this build is so that I can take advantage of PWM on the Arduino and the fact you can change the frequency of the PWM easily within a sketch.
I can manage getting 240vac to a smooth DC form just fine, there is plenty of info out there to take care of that.
What I'm struggling with is the choice of mosfet and driver. There is like a billion to pick from.
My basic parameters are:
+/-240vdc. Not sure what the out come will be so I figure a mosfet rated for 650v should cover all bases.
1-5 amps. This is a testing rig so may draw up to 10 or 15 amps on occasion.
Switching ability. I'd like to set the PWM frequency anywhere between 50Hz and say 100,000Hz or more if possible.
Type of electrical load, I'm unsure of. What I'm running will be an electrolyzer. I don't know if that's classed as inductive or not.
I'm hoping for a little guidance on gate driver and mosfet selection. Here is what I have in the shopping trolley at the moment. Do you think they will work??
Please let me know if you need more info but I'm not sure what else to supply at this point.
