Half-wave unregulated power supply

Design a half-wave unregulated power supply to give VL = 15V at IL = 10mA with deltav <= 0.1V. Assume a 120V, 60Hz supply. What is the regulation of the power supply?


Solution Preview

Input voltage = 120 V
Output voltage (VL) = 15 V

It is clear that output voltage will be the peak voltage = (Vp_out) = 15 V
Input peak voltage (Vp_in) = 120*sqrt(2) = 169.7 V

Hence, turns ...

Solution Summary

"... after filtering through capacitance, there is output dc voltage with ripple (0.1*100/15 = 0.6%)."
