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 ground in order to keep the battery voltage constant. This principle works well for small to medium-sized 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 demands of modern motorcycles and quads are constantly increasing due to additional electronic modules: injection, high-efficiency lighting, and various accessories. This involves a significant amount of energy from the generator. The traditional regulator cannot meet this demand due to its low energy efficiency. The internal losses of the regulator lead to overheating and damage when conducting currents over 35A. The traditional regulator has reached its limits and is not recommended for high-capacity vehicles with high energy consumption.

A traditional regulator exhibits a high voltage drop (about 1.5V at 35A) as it operates like a power diode. As the current increases, the power dissipated (heat) grows linearly. With the new MOSFET regulators, the voltage can be modulated like a controlled switch, with a different semiconductor architecture that makes them more efficient in energy management. When active, it behaves with great power and offers a very low resistance that diverts all the excess current from the generator to ground. The voltage drop is therefore 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 long lifespan of the regulator.

The MOSFET technology has been continuously improving for several years, due to its widespread application in the electronics industry. The integration of semiconductor techniques offers 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 avoid overheating. The internal controller has been completely redesigned to meet driving needs. The battery voltage is monitored continuously to adjust the output current in different energy consumption situations. The new electronic control avoids the use of linear ignitions, reduces the number of connections, and simplifies the wiring topology. It also incorporates a very low power sleep mode, which prevents battery drain when the vehicle is not in operation. A MOSFET regulator can increase the output current up to 50A, with optimal voltage regulation and additional advantages: reduced heat, high efficiency, and advanced electronic control. This new technology is the best option for managing the vehicle's charging system.
