How Do Energy Flow Control Systems Work?

AI Thread Summary
Energy flow control systems utilize electrical signals to manage energy distribution, commonly seen in applications like sewing machine motors controlled by foot-operated variable resistors. The discussion suggests using block diagrams for clarity in explaining these systems. It highlights that all control systems have inefficiencies, consuming a portion of energy in the process. The conversation emphasizes the importance of clearly presenting the operation and limitations of these systems. Understanding these factors is crucial for a comprehensive analysis of energy flow control systems.

An energy flow control system is one where electrical signals are used to control the flow of energy. quite often electrical energy. A modern example of one such system is the manual control of the speed of a sewing machine motor by way of a foot opearated variable resistor and switching semiconductor device. Analyse and discuss the operation of such a system.

Would I be best explaining this system using a network type of diagram or should I do it some other way. Any suggestions on what I should talk about would be appreciated.

I'm not sure what level your talk is at.

I prefer block diagram presentations.

You might mention that all such control systems are imperfect and that they consumer a fractio of the energy themselves.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

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...

Thread 'Following up on the recent thread about Earth Resistance measurements'

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...

Thread 'Question about bonding ground and neutral'

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...
