The scenario
A hand-crank dynamo produces low-voltage AC that must be rectified and smoothed to power a DC load reliably.
What is in this drawing
Read the decisions behind it.
01
Use a full-wave diode bridge for efficient conversion of both AC half-cycles
02
Place a large electrolytic capacitor across the DC output to reduce ripple
03
Reference the system to a common 0V ground rail
Reuse this pattern for any low-power AC generator, bicycle dynamo, or small wind-turbine supply needing clean DC output.
