Paralleling PWM outputs and sensor inputs
Posted: Fri Jan 31, 2020 6:40 pm
Hi Johannes
I have here 2 600A power stages in one casing. Since we now know your software reliably works i propose a crazy idea.
What if i would parallel both sides of Volt inverter?
My plan is the following:
1. I will use two inverter chips SN74LS06 and ill feed them from a single input being Olimex STM32 chip.
2. I will also parallel current sensor inputs. Volt inverter current inputs are allready all in one place. Now to do paralleling i propose to feed from each symmetrical sensor signal each through a 2K2 resistors then join that 5V signal and pull it down by 3K3 resistor. That will again form divider 1K2/3K3. By then signal will be muxed and if any sensor will go off chart it will trip OC circuit because of misproportion. Do you think it will work?
