I have a motorcycle which i want to install hid light.
normally motorcycle has small wet battery 3,5Ah, 12V. and its current is AC.
the power for this HID light is 35 Watt and need current DC
based on data above my battery will become empty and after that the engine can not on by electric starter.

would you give me schema/circuit for regulator full DC which can change the current from AC to DC and also to increase the charging of battery without modify anything, what i mean is by using this regulator AC become DC, increasing battery charging without increasing voltage.

please help me and send the scheme/diagram with the component including the size to siallagan@gmail.com

The voltage of my actuator is 2 volt and its current is 200 mA. can anyone help me with this? Hi

I have tree times asked for the pcb for 11-90Hz sub-filter, and were to by it, but got no answer. The sub-cabinet widt speaker, and power amp. is ready. Can sombody help me, I am going to be happy. Kind regards Ib Kjer hello!

But it needs like a dual supply input voltage. (inputs like a solar cell (12dc) and windmill (12DC) So it there is no wind the solar panel will change the battery and if there in no sun the wind will charge the battery.. and if there is wind and sun no problem... Just don't wanna swap or anything all the time... Sorry for the long story, in Afrikaans, and most of the time people don't know that i mean.
