Okay, here's what I have :
- a 6V/3W dynamo (Dymotec S6 which gives a constant output of 6V from a speed as low as 10km/h=6mph)
- a white Cree XR-E LED for front light (measured 3.18V at 350 mA)
- a red Cree XR LED for tail light (measured 2.08V at 350 mA)
I want to drive both LEDs in series (they can be overdriven since they are both capable of being driven at upto 700 mA). Now I need a rectifier to convert the dynamos alternating current (AC) to direct current (DC) but I don't know much about making a rectifier. So how do I have to construct an efficient rectifier and which parts do I need and where can I get them?
Thanks for your help!
