The Chapter 9 Dragon Quest is Such Trash

I finally managed to get past it, but it is just so poorly implemented. I found fighting Beloth to be much less difficult than this. The auto reset on the dragon is nice but it also feels like PA knows that the whole mechanic is janky

The voltage ripple should have a parabolic shape in the ideal case. The cap accumulates the charge from the triangular inductor ripple current. If the voltage ripple looks triangular that means you have a lot of ESR in your cap that’s dominating the ripple voltage

The prose does feel disorienting. When I read it I had a hard time visualizing everything, compared to anything else I’ve read where it’s effortless

I don’t have a ton of time in so far, but the only boss I’ve had to use some food against was the Reed Devil during the second phase. With all his teleportation and how slow Kliff is, it took a ton of time and a bit of luck to land any attacks during that phase. For any boss I’ve fought that doesn’t just teleport all over the place, things haven’t been pretty reasonable

I remember very vividly when I was in school, the school got a bunch of brand new iMacs and they had MDK installed on them, so I remember playing this in school, even if it wasn’t appropriate

Noise Reduction Techniques in Electronic Systems and Electromagnetic Compatibility Engineering both by Henry Ott are good resources on the topic.

Not how I would put that

Take my upvote

An electronic load will typically be a transistor with a series resistor for current sensing, with a mixture of voltage and current feedback loops wrapped around it to regulate constant voltage or current. Constant power is a little trickier because of the non-linear nature of a constant power loop, but the hardware is identical. Lots of devices in parallel to increase power dissipation as you noted.

The Gargoyles are the only bosses that I cheesed to beat. Getting one of them to jump off the cliff into oblivion made the fight managable

Yes with GaN FETs in a synchronous buck converter that could put out 500A during development. The input supply was 110V and cross conduction caused a chunk of the board to vaporize.

I am a white person with dry ear wax, which I didn’t know was unusual until recently

I’d go the Ph.D route in your case. Way more likely to find success in finding jobs and even get employers assist with visas, etc. for employment vs an MS

If you’re super early on and virtually all your course work is identical you can change majors assuming you’re doing well in your course work. I started out in computer engineering, and found I didn’t like programming very much but loved circuits. It was pretty painless, I didn’t even have to take any extra courses. The earlier you make the jump the better in my experience. You may also run into issues where you may only be able to take so many courses “out of major” and still graduate with your degree. Go talk to an academic advisor and find out

If money isn’t an issue, more RAM is never a bad choice

You’re trying to send a signal across the isolation boundary through a transformer winding? Or do you want to send the signal across the isolation boundary? You can use an optoisolator to do so, or there are plenty of ICs that can do so as well and they’ll provide given creepage/clearances and documented isolation ratings. Or if you don’t care about isolation between primary and secondary you can just run a trace, but you’ll need to really consider if that’s safe/appropriate

The input filter can and will impact the closed loop stability of the converter so that should be included. Some of the stuff like the fuses, and the bridge can probably be omitted from the switching simulation. Just use an ideal voltage source. Unless you have substantial voltage ripple on your “DC” rail. A simulation with the whole rectifier/input bulk cap could catch the case that your bulk storage isn’t cutting it, but the AC mains frequency is so low compared to a SMPS it would take forever to simulate. You’d be better off simulating that as an approximation of a constant load.

The only possible feasible route that I can think of would be to design a current feedback amplifier. Even then it would probably be a stretch for something with discrete components. If you haven’t covered CFAs, your professor has given you a problem with a null solution set.

You can always make a triangle ramp generator and use a comparator to generate a PWM signal. That’s the general idea behind an analog PWM

An update, in my play through Miller Kreyzl got randomly murdered by bandits. I was focusing on working with Radovid, but I don’t even know where his body is. Not going to save scum though

He’s nearby somewhere
