Bicycle power supply with full-wave and half-wave charging elements

摘要

A charging apparatus (1) comprises a rectifying circuit (5) for rectifying the alternating current from the bicycle dynamo (2); a full-wave charging element (6) operatively coupled to the rectifying circuit (5) for charging during both positive and negative half-cycles of the bicycle dynamo (2); a first half-wave charging element (7) operatively coupled to the rectifying circuit (5) in parallel with the full-wave charging element (6), wherein the first half-wave charging element (7) charges during positive half-cycles of said dynamo (2); and a second half-wave charging element (8) operatively coupled to the rectifying circuit (5) in parallel with the full-wave charging element (6), wherein the second half-wave charging element (8) charges during negative half-cycles of the dynamo (2).
