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 (SCR) to divert excess energy from the generator to the ground to keep the battery voltage constant. This principle works fine for small to medium-sized internal combustion engines. However, the new regulator technology based on MOSFET transistors is becoming 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 involves a significant amount of energy coming from the generator. The traditional regulator cannot meet this demand due to its low energy efficiency. Internal losses in the regulator cause overheating and damage when conducting currents over 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 works like a power diode. As current increases, the power dissipated (heat) grows linearly. With the new MOSFET regulators, voltage can be modulated like a controlled switch, with 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 the ground. Therefore, the voltage drop is very low (less than 0.2V at 35A) and heat is drastically reduced. This is directly linked to less heating of the device and a longer lifespan of the regulator.

The MOSFET technology has been continually improving over the years, due to its widespread application in the electronics industry. The integration of semiconductor techniques provides superior power in compact spaces with excellent efficiency. It also allows for faster switching, increased reliability, and optimal control in 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 the output current under different energy consumption situations. The new electronic control avoids using linear ignitions, reduces the number of connections, and simplifies the wiring topology. It also integrates a very low power standby mode, which prevents battery drain when the vehicle is not running. A MOSFET regulator allows for an output current increase 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.
