Or with both ? --- End quote --- In order to resolve disagreement, we need proof. Ltspice simulation can be used as proof. --- End quote --- As I mentioned above for question A) it will be you that needs to provide the proof. The question B) I explained in details so it should be sufficient proof but it can be arranged to be simulated in LTspice tho it will take time as it is a relatively complex simulation due to switch logic involved. They should likely already have some DC-DC boost converters with max power point tracking so that part should be easy. I provided spice simulation as proof for the Veritasium video on how electricity works and it was of no help. If people do not understand the basics a simulation or even an real experimental demonstration will not help with anything and cost me time. |

--- Quote from: electrodacus on December 29, 2023, 05:24:17 am ---A) Is it possible for V2 to be a constant 30V? No B) Is it possible for V2 to peak to 30V multiple times while V2 never drops below 5V ? Yes So do you not agree with one of my answers ? Or with both ? --- End quote --- Now that you have stated a somewhat clear question who has disagreed with you? No-one! So why immediately ask if every poster agrees/disagrees? |

Power, voltage, signal flow from left to right and from top to bottom. I often redraw schematics that way because it helps me analyze and understand the circuit. When I reverse engineer a circuit I start out with a schematic which resembles the PCB but I rearrange it in steps until it is easier to conceptualize. |

(see original post as it was edited recently and the two questions where added). --- End quote --- ... and there we have it. Changing the post to make it look like people are disagreeing with you. There was no need to edit the original post when you can just add your new argument inline. Now we'll have to aggressively quote everything you say to keep the discussion coherent. --- End quote --- The post change can not make people agree or disagree with me. It is to make it simpler to answer with Yes or NO to A) and B) Those that answered before the two questions where added never mentioned A) or B) The question was always the same and yes people where not all in agreement with me or with others before or after I added the questions to original post. It is a problem and based on feedback I can improve the formulation to make thing more clear. So what is your answer ? --- End quote --- The acceptable way to change your opinion is: * add a new post indicating your new opinion * optionally changing the early post, using strikethrough to indicate what you no longer wish other people to consider, and adding "EDIT: ..." to show your new opinion. Doing that makes you appear to be thoughtful and considerate. "Silently" changing the early post makes you look like an insecure troll. |

--- Quote from: electrodacus on December 28, 2023, 01:33:45 am ---There were people in the past that disagreed with the fact that V2 can not be continuously higher than V1 despite the floating GND. --- End quote --- You would need to provide a context reference for that statement, by quoting instances where "people in the past" said this. |
