| Mar 15 at 5:48 | comment | added | Dmarm | regarding pwm as feedback, this requires a voltage to frequency converter, right? What is the advantage of this approach compared to measuring voltage using an ADC? | |
| Mar 15 at 5:45 | comment | added | Dmarm | I tested the converter with a 1k resistor as a load since 100V/100mA=1kOhm. It is not on the figure, as I took the screenshot after adding the voltage divider. | |
| Mar 15 at 2:17 | comment | added | Jasen Слава Україні | figure 1 seems to be missing any load on the converter output, did you test the converter under the expected load? | |
| Mar 15 at 2:15 | comment | added | Jasen Слава Україні | I would consider starting with a proven boost converter circuit and then using the PWM signal to distort the feedback. | |
| Mar 15 at 0:54 | comment | added | Colin | From your description it sounds like you not only want to boost the voltage, but also monitor it. I think you're on the right track but I'm thinking of a way that you can monitor your voltage. That's going to be a challenge. A voltage divider could work but the accuracy is not going to get very desirable results because you're squeezing 100V to fit inside of a 0 to 3.3V measurement scale. | |
