Question
What is the full-load voltage of a power supply has a voltage regulation of 1%. If the no-loadvoltage is 20 V
Solution
The voltage regulation of a power supply is defined as the percentage change in output voltage from no-load to full-load conditions. It is given by the formula:
Voltage Regulation (%) = [(No-load Voltage - Full-load Voltage) / Full-load Voltage] * 100%
Given that the voltage regulation is 1% and the no-load voltage is 20V, we can rearrange the formula to solve for the full-load voltage:
Full-load Voltage = No-load Voltage / (1 + Voltage Regulation/100)
Substituting the given values:
Full-load Voltage = 20V / (1 + 1/100) = 20V / 1.01 ≈ 19.80V
So, the full-load voltage of the power supply is approximately 19.80V.
