For how popular motorcycles are, the types and elements utilized in them are likely to change a lot a lot more wildly than in cars and vehicles. Often this is to the rider’s benefit, like Honda experimenting with airbags or computerized transmissions. In some cases it is a little additional questionable, like sure American brand names holding on to pushrod motor styles from the ’40s. And sometimes it is just bothersome, like the use of low cost voltage regulators that fail normally and carry out poorly. [fvfilippetti] was worn out of dealing with this on his motorcycle, so he developed a customized voltage regulator applying MOSFETs as an alternative.

In contrast to a fashionable vehicle alternator, which can create usable voltage even at idle, smaller or older motorbike alternators usually just cannot. In its place they count on a less complicated but fewer reputable regulator that is typically no extra than a collection of diodes, but which can only produce power to the electrical system whilst the motor is working at greater speeds. Hoping to strengthen on this style, [fvfilippetti] made a switched regulator from scratch out of MOSFETs with some interesting design and style concerns. It is capable of having an input voltage between 20V and 250V, and enhances the capability of the motorbike to use modern-day, larger-energy lights and to charge units like phones as effectively.

In the video down below, an LED was additional in the circuit to give a visual sign that the regulator is operating adequately. It is surely a welcome make for anybody who has at any time dealt with rectifier- or diode-model regulators on more mature bikes right before. Automobile alternators are attention-grabbing beasts in their have correct, much too, and they can be made use of for a great deal much more than managing your motorcycle’s electrical process.
