Write a report on the operation of power supply units. Your reports must contain information on four stages of a PSU – transformers, rectification, smoothing and regulation. More importantly it should include load regulation. E.g. what happens to the output voltage/current if the load varies.
Basically I have done everything except the last part where it says 'what happens to the output voltage/current if the load varies'
can u please help?
Thanks.
@Dhrubo,
Dhr it's called "regulation." In a regulated supply the output voltage or current is more nearly constant without which of course we'd ordinarily expect a drop with increasing load; but how can we be of further help
@dalehileman,
The output voltage should remain the same so that the components that the PSU is supplying will continue to work properly within their design limits.
The output current will change change automatically as the load changes, if the load goes up the ( the resistance of it goes down ) the current will rise and vice versa, Ohms law.
is this correct?
@Dhrubo,
Yes Dh
Can we be of any further assistance
