For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Find the difference between the initial voltage and the maximum fluctuation. For example, if the initial voltage was 25 and the maximum measurement was 28, then the difference in voltage would be 3 volts. Divide the change in voltage by the initial voltage. Multiply the number obtained in Step 2 by 100.
What is the formula for line regulation?
The line regulation is given by the equation shown below. Where |VRML | = magnitude of receiving end voltage at no load. |RFL| = magnitude of receiving end voltage at no load. The regulation of the line depends on the power factor of the load.
What do you mean by line regulation?
Line regulation is the ability of the power supply to maintain its specified output voltage over changes in the input line voltage. It is expressed as percent of change in the output voltage relative to the change in the input line voltage.
What is the difference between line regulation and load regulation?
Line regulation is the ability to maintain specified output voltage over changes in the input line voltage. Load regulation is the ability to maintain specified output voltage over changes in the value of the load.
What is line regulation in Zenger diode?
Line regulation refers to the amount the voltage varies at the output due to variations in the input voltage (line). The voltage drop of a Zenger diode does vary a bit with current changes, so both line voltage and load current cause small changes in output voltage.
What does line regulation mean?
Line regulation is the ability of the power supply to maintain its specified output voltage over changes in the input line voltage. It is expressed as percent of change in the output voltage relative to the change in the input line voltage.
What is meant by line and load regulation?
Line regulation is the ability to maintain specified output voltage over changes in the input line voltage. Load regulation is the ability to maintain specified output voltage over changes in the value of the load.
What is line regulation formula?
Line regulation. In practice, a well regulated power supply should have a line regulation of at most 0.1%. In the regulator device data sheets the line regulation is expressed as percent change in output with respect to change in input per volt of the output. Mathematically it is expressed as: The unit here is %/V.
