I was just wondering if anyone out there had looked at part (a) for the Boost ACM problem from HW10. I'm a little confused on exactly what parameters we can set for the sawtooth since the switching frequency and the amplitude are given.
I'm thinking it has something to do with the minimum voltage of the sawtooth. I've read the papers on ACM posted online, and Dixon makes it seem like the slopes need to be the focus, though we have no control over these.
The problem does say to just sketch the "waveshape," so perhaps numbers are not important?
Anyways, can anyone point me in the right direction?
Thanks,
Danny
Part a): I think we can set the slope of the saw-tooth waveform to be either positive or negative. That is the parameter we can set. The goal is to get negative feedback.
ReplyDelete- Slope of the PWM saw-tooth waveform vt(t) is set by Vm and fs.
- Slope of the vm(t) depends on the iL slope and compensator parameters. vm(t) slope can be controlled by changing the compensator parameters. This is part c) of the problem.
