battery charge regulator phase _1 motorcycle

You know how a battery charge controller for motorcycles?, I once asked a mechanic who was visiting from time to time just for a chat and take a visual the machines had in his hands.
Well I think if I responded. We have five quads were burning standing because regulators were Chinese and did not find any spare, you could give them a visual, he said, was impossible to repair, among other things because the circuitry is encased in a hardcover hard, hard, and so it was that started this project.
medium displacement motorcycles are fitted up with a star alternator, which most mechanics known as "on."
The alternator generates three phase alternating current is rectified by a bridge rectifier to get DC power suitable for charging a battery up there all right. If measures are
voltage at the terminals of alternator Start the engine and idle, voltage can be measured about 12 to 14 volts depending on the type of alternator when the engine revs, the tension rises proportionally voltages reaching of about 70volts or even more, it is obvious that if you apply more than 15voltios a 12v battery. inevitably die, that's not counting other damage to the electrical system such as electronics or light bulbs cast as the ignition CDI or TCI that pain!
So a charge controller, apart from rectifying the alternating current in continuous need to maintain voltage at a constant level regardless of engine speed to reach the engine. At this point it is logical that the main objective would be
"go turning the tap off the alternator to work up speed" and thereby attain the charging voltage for battery always be maintained between 13.8 and 14.2 volts.
taking measures in different motorcycles I realized that not everyone is charged the same rate of loading, about 13.6 V. other 13.8 to my xv 1100 Virago regulator applied to 14.1 V.
Then it occurred to me as I was on the donkey, the regulator would make would be for a fixed charging voltage variable but I've noticed that the postman does not turn off the new scooter with electric start when it comes to email, That is because if the off and on continuously loses power, need a higher charge rate, in contrast to others, like me, who do I start the bike hit forty miles and when I reach my destination the strike.
to "close the tap" to the alternator, I used thyristors, phase one, I mean three 20 Amp.

The thyristor is a semiconductor device that has three pins, to explain in plain language: an input pin A, another output and a control K G. When no voltage is applied to pin G control, the device behaves as if it were not, if voltage is applied to the device conducts current G is proportional to the voltage applied to G, we have the "tap" that opens and closes. Another
control circuit consists of several transistors, zener diode, resistors, etc, is responsible for testing the battery voltage, this circuit is which sent more or less voltage to pin G of the thyristor "which controls the tap." It is in this circuit where, by an external regulator sets the charging voltage that is desired for the battery, from 13.6 to 14.2 volts.
Another important component is the bridge rectifier, I used a 30 amp, more than enough.
The greatest enemy of semiconductors is the heat they generate, I had to choose a sink-radiator at the same time I serve for the assembly of the components inside, so you got a compact, choose those that are used in audio power amplifiers.
