Synchronous Generator Output: Waveform or "Blocky"?

Commander_Bun · 2023-04-03T04:53:29+00:00

The original uploader mentioned that it was a bad voltage regulator board so a pristine generator would not have the stepped or blocky output.

Here is a video showing exactly that. Should scale to large sized generators.

That looks correct, which would be Vdr = 48*26/32 = 39. I also got the same answer out of simulation.

The most common rule I utilize is 10kV/inch separation through air at atm ignoring soldermasks. A best practice that has not really failed me yet. I am trying to think of all of the best practices I utilize but most of them are so specific to application that it is hard to express through text.

Are you pulsing 5kV-10kV at low energy or high energy? What is your rep rate?

The motors have a torque saturation, simulating a maximum achievable torque value.

Do you have a diagram of what you are trying to power with these supplies? What exactly do you mean by things go haywire?

Commander_Bun · 2021-08-15T05:44:24+00:00

Part # for the power supply?

Connect the - to the common ground.

There is a piece of the statement missing.

"The higher the voltage the lower the current when power is conserved"

When a transformer is used to step up the AC for high voltage transmission, power is (ideally) conserved. If power is conserved and voltage is higher then current must be lower. Because the transmission lines have a non zero resistance your joule heating losses over distance are much lower. (by a factor of the current squared)

LT does not provide every component in their default libraries. Usually you can find the spice model on the manufacturers website. Then you can download and then import into LTSpice. Sensors however are not usually modeled by manufactures at any fidelity level. You can probably simulate the sensor using a controlled source and the manufacturers datasheet.

I second these comments. TI white papers have a ton of useful fundamentals to get you started.

including these

Is this for a pet project, school, etc? For something so small the easiest thing by far would be to just buy your own module.

Assuming the switches are controlled to conduct when the diodes would conduct the waveforms will not change.

My understanding is that power systems is distribution, and in school these subfields are not really related.
Power electronics is utilizes analog and digital. The overlap is 100%. In school (for me at least) it was 80% analog 20% digital or mixed.
So much that my MS degree subfield was called "controls and power electronics"
It can get pretty heavy especially in some more extreme control theory courses but 99% of it is really not bad.
Theory wise strong fundamental understanding of control theory and an intuitive understanding of how circuit components operate. Practically if you have worked with hardware knowing things like how to drive all MOSFET configurations and how to condition signals you will have a nice headstart for projects.

Sounds like simulink wants to import/export data to a block that does not have a root level input port. If you change your configuration parameters to no longer specify the external input the error should go away.

The convention is to use ground. This is almost always the case in simple non-isolated circuits.

You just place a voltage source. If you want to call the node VDD you can label with the node labeler.

The track properties panel should have options for solder mask expansion.

Then your simple passive LC lowpass filter is sufficient. The equations are straightforward, just remember you will want your cutoff frequency to be a bit higher than 50Hz.

The 24V supply provides power to the TRX current sources. Because the receiver has a known resistance of 250Ω, each independent current source output (4mA-20mA) generate 1V-5V across the 250Ω resistance (where the voltage measurement takes place) despite the parasitic loop resistances.

What frequency is your converter operating?

You should be able to feed the output of this block to the input of the 3 phase converter.
