Hello!
I'm currently designing a regulator circuit for my motorbike. I've been doing work on shunt regulators, but it seems to be producing lots of heat, and I can't figure out how to make it work.
Here's the scenario:
1. My motorbike (Yamaha Mio 110cc) has a permanent magnet that spins around a stationary stator. 2 wires that comes out from the stator, a yellow wire and a white wire, I guess this is not a 3 phase system.
The yellow wire seems to be a low current battery charging source, while the white wire seems to carry a high current.
What I do to rectify the AC voltage (white wire + chasis body ground) is I simply put a diode on the white wire (half wave). I was trying to use a full wave bridge rectifier but the bridge diodes seems to overheat when i connect the Negative side of the bridge to ground.
during Idle my bike produces around 20vAC and when in high rev it produces around 50vAC. When I try to use a shunt regulator on the high current (white) wire, everything seems to be to hot, so I guess the shunt regulator would not be a good way to control voltage.
I need to control that 20v-50v AC and get 12v-14v out of it. I hope you can help me out.
