This is some kind of chopper. link. But what physics problem does the chopper is a solution for?

Actually I can, but the problem statement is in Bulgarian, but the schematic is the same, as shown in the statement. The prof said this is used in device which is used for 50 years till today. The schematic is this I've just redraw it with software. First: I have to measure the voltage drop on...

I think Cv and Ch are in series in the first half of the image, which represents the U,u position of DPDT switch.

Today, I said that this can be used as a rejecting circuit to reject common voltage and to detect differential-mode voltage, to my professor. And his reply was: "Of course it's not. Keep working. The man who developed the application of this circuit has became very rich." Is there some relation...

In the problem statement it's said that I have to measure the voltage across Cv, while switching from D,d to U,u. The maximum voltage across Cv, which can be obtained is +1,5V which is equal to e. I can explain this, but as gneil said this is some kind of "charge pump". I was asked from a...

Homework Statement Hi all, My question is: In what kind of device the enclosed schematic can find an application? The bipolar switch has two positions U and u- which are for upper position and D and d- which are for down position. The main question is on what kind of equation the voltage...
