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 and medium displacement internal combustion engines. However, the new regulator technology based on MOSFET transistors is gaining popularity 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: injection, high-efficiency lighting, and multiple 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 cause overheating and damage when conducting currents above 35A. The traditional regulator has reached its limits and is not recommended for high-displacement high-energy consumption vehicles.

A traditional regulator has a high voltage drop (about 1.5V at 35A), as it operates like a power diode. When 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 high power and offers a very low resistance that diverts all 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.

MOFSET technology has been continuously improving for several years, due to its extensive application in the electronics industry. The integration of semiconductor techniques provides higher 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 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 integrates a very low power sleep mode, which prevents battery charge loss 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.
