Regulator/rectifier with MOSFET technology

Spare part in original quality

This new technology has innovated the concept of three-phase ladder regulators. For many years, these devices have used silicon controlled rectifiers (SCR) to conduct the excess energy from the alternator to ground in order to keep the battery voltage constant.

This was generally accepted and proved adequate for small and medium sized alternators in internal combustion engines. However, the new regulator technology based on MOSFET transistors is becoming increasingly popular due to better performance and many other interesting advantages over SCR.

The energy demand in modern motorcycles and ATVs is increasing nowadays due to the use of additional electronic modules such as fuel injection system, high efficiency lighting, numerous accessories etc.. This means a large amount of energy coming out of the generator and the SCR shunt regulator is not able to regulate it.

The main reason is the low energy efficiency, the internal losses of the regulator lead to overheating and premature damage when currents greater than 35A are passed through the regulator. As a result, SCR technology has reached a limit and is therefore not recommended for large vehicles with high energy consumption.

To solve this previously mentioned problem, it was necessary to reduce the losses in the circuit. When the SCR is active (generator current to ground), there is a high voltage drop in the forward direction (approx. 1.5V @ 35A), as it functions like a power diode. If the current now increases, the power loss (e.g. heat) increases in parallel.

POWER LOSS OF THE DEVICE (W) = FORWARD CURRENT (A) X VOLTAGE DROP (V)

Advantages:

- 3-PHASE SHUNT REGULATOR WITH HIGH ENERGY EFFICIENCY

- OUTPUT POWER UP TO 50A

- PRECISE ELECTRONIC CONTROL OF THE BATTERY VOLTAGE PREVENTS MISFIRING

- LOWER HEAT DEVELOPMENT LEADS TO LONGER SERVICE LIFE

- LOW-POWER STANDBY MODE WHEN VEHICLE IS NOT IN USE

Unlike other transistors, MOSFET transistors can be characterized as voltage-controlled switches because their completely different semiconductor architecture makes them more efficient in their use of energy.

When in use, they behave like a resistor with a low nominal value for high currents, conducting all the excess current from the generator to ground. As a result, the voltage drop is very low (less than +/-0.2V @ 35A) and power dissipation is drastically reduced. This has a direct effect on less heating of the device and a long service life of the regulator.

MOSFET technology has been continuously improved in recent years due to its wide application in consumer and industrial electronics. Semiconductor integration technology offers higher power handling in reduced space with excellent efficiency. In addition, they enable faster switching, higher reliability and better control under high loads.

Rectifier diode performance is another important factor when it comes to power dissipation. Because all the output current flows through them, they need to offer both great robustness and stability, as well as efficient current control. Our MOSFET regulators use high current enhanced rectifier diodes with extremely low voltage drop, which help to avoid overheating and meet the previously mentioned requirements.

The internal CONTROLLER has been completely redesigned to match the requirements of the MOSFET transistor. The battery voltage is constantly monitored to adapt the output current to the different consumption situations. The new electronic control avoids the use of the ignition cable, reduces the number of connections and simplifies the cable topology. It also has low energy consumption in standby mode, resulting in very low battery drain when the vehicle is not in use.

This new technology therefore makes it possible to increase the output power of the regulator up to 50A while maintaining excellent voltage regulation. Additional advantages such as reduced heating, high efficiency and advanced electronic control make this new regulator the first choice for controlling your vehicle's battery circuit.
