AI Thread Summary
The discussion focuses on designing a reconfigurable rectifier circuit that can operate in either a 2-stage or 3-stage configuration based on output voltage, which varies with the distance between a reader and a tag. The user seeks advice on how to implement this flexibility, particularly in choosing between the second and third stages of the rectifier depending on the output voltage. Clarification is requested regarding the term "stages" in the context of rectifiers, with a reference to the Cockcroft-Walton multiplier. The user has also attached a circuit diagram and is looking for suggestions on modifications to enable the reconfiguration. Overall, the goal is to optimize the circuit's performance based on proximity between the reader and tag.

Hi,

I had designed a rectifier with 4 stages. I want to design a re configurable circuit in such a way that I can use either 2-stage or 3-stage of the rectifier depending upon the output voltage.
Output voltage depends on the distance between reader and tag. If both are near, then the output voltage is higher and sufficient to initialize the circuitary within the tag. So, at that instant, the output voltage at second stage is enough for me. In case, tag and reader are farther, I may need 3 stages of rectifier. Depending upon the output voltage at the second stage, I can have the flexibility to chose either second stage or the third stage. In such scenarios, please suggest me how to design a reconfigurable circuit for stage 2 and stage 3?

What do you mean by "stages" in a rectifier? Are you using something like the Cockcroft-Walton multiplier?

I have attached the circuit. Now, tell me what circuit can be added so that I can reconfigure the circuit either to 3-stage or 4-stage.

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
