This hand dynamo is suitable for charging for small accumulator, therefore, it needs to change alternating current to direct current and it should commute and filtering.
The schematic diagram of circuit is as following:

F: Dynamo, there is no phase sequence for three output leads that can connect with D at random
D: Diode
C: Electrolytic capacitor
