MOSFET: technological revolution of regulators

The MOSFET transistor amplifies electronic signals. This technology has revolutionised the concept of the three-phase regulator. For many years, traditional regulators used silicon controlled rectifiers (SCRs) to divert excess energy from the generator to ground in order to maintain a constant battery voltage. This principle works well for small to medium displacement thermal engines. However, the new regulator technology based on MOSFET transistors has become popular due to its optimal performance and many other advantages.

The energy demand of modern motorcycles and quads is constantly increasing due to additional electronic modules: fuel injection, high-efficiency lighting, and various accessories. This implies a significant amount of energy from the generator. Traditional regulators cannot meet this demand due to their low energy efficiency. Internal losses in the regulator cause overheating and damage when conducting currents above 35A. The traditional regulator has reached its limits and is not recommended for high displacement vehicles with high energy consumption.

A traditional regulator has a high voltage drop (about 1.5V at 35A), as it functions like a power diode. As the current increases, the dissipated power (heat) grows linearly. With the new MOSFET regulators, the voltage can be modulated like a controlled switch, featuring a different semiconductor architecture that makes them more efficient in energy management. When active, it operates with high power and offers a very low resistance that diverts all excess current from the generator to ground. Hence, the voltage drop is very low (less than 0.2V at 35A) and heat is drastically reduced. This is directly related to less heating of the device and a longer lifespan of the regulator.

The MOSFET technology has been continuously improving for several years due to its extensive application in the electronics industry. The integration of semiconductor techniques offers greater power in compact spaces with excellent efficiency. It also allows for faster switching, increased reliability, and optimal control under adverse conditions.

MOSFET regulators use improved current rectifier diodes with an extremely low voltage drop, which helps prevent overheating. The internal controller has been completely redesigned to meet driving needs. The battery voltage is continuously monitored to adjust output current in different energy consumption situations. The new electronic control avoids the use of linear ignitions, reduces the number of connections, and simplifies wiring topology. It also incorporates a very low consumption sleep mode, preventing battery drain when the vehicle is not in operation. A MOSFET regulator enables an output current of up to 50A, with optimal voltage regulation and additional benefits: reduced heat, high efficiency, and advanced electronic control. This new technology is the best option for managing the vehicle's charging system.
