Regulator/rectifier for Aprilia,piaggio Motorcycle 2010-21

Description

This new technology has renewed the concept of the three-phase ladder regulator. For many years these devices have used silicon controlled rectifiers (SCR) to direct the excessive energy from the generator to ground and thus keep the battery voltage constant.

This has been widely accepted and has been found to be adequate for small and medium-sized generators in internal combustion engines. However, the new regulator technology based on MOSFET transistors is becoming increasingly popular because of its better performance and many other interesting advantages over the SCR.

The energy requirement in modern motorcycles and ATV is increasing nowadays due to the use of additional electronic modules such as injection systems, highly efficient lighting, numerous accessories, etc. This means a large amount of energy coming from 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 if 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.

In order to solve the aforementioned 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) because it works like a power diode. If the current increases, the power loss (e.g. heat) increases in parallel.

DEVICE POWER LOSS (W) = THROUGH CURRENT (A) X VOLTAGE DROP (V)

Advantages:

– 3-PHASE SHUNT CONTROLLER WITH HIGH ENERGY EFFICIENCY

– OUTPUT POWER UP TO 50A

– PRECISE ELECTRONIC CONTROL OF THE BATTERY VOLTAGE PREVENTS IGNITION FAILURES

– LESS HEAT DEVELOPMENT LEADS TO LONGER SERVICE LIFE

– LOW POWER STANDBY MODE WHEN VEHICLE IS NOT USED

In contrast to other transistors, MOSFET transistors can be designed as voltage-controlled switches, because a completely different semiconductor architecture makes them more efficient in handling energy.

When in use, they behave like a low-rated, high-current resistor that directs all of the excess current from the generator to ground. As a result, the voltage drop is very low (less than +/- 0.2V @ 35A) and the power loss is drastically reduced. This has a direct effect on lower heating of the device and long service life of the controller.

MOSFET technology has been continuously improved in recent years because of its wide application in consumer and industrial electronics. The semiconductor integration technology offers a higher load capacity in reduced space conditions with excellent efficiency. In addition, they enable faster switching, higher reliability and better control under heavy loads.

The rectifier diode performance is another important factor when it comes to power dissipation. Because all of the output current flows through them, they must offer great robustness and stability as well as efficient current control. Our MOSFET regulators use high-current improved rectifier diodes with extremely low voltage drop, which help prevent overheating and meet the aforementioned requirements.

The internal CONTROLLER has been completely redesigned to adapt it to the requirements of the MOSFET transistor. The battery voltage is constantly monitored in order to adapt the output current to the various consumption situations. The new electronic control system avoids the use of the ignition cable, reduces the number of connections and simplifies the cable topology. It also has a low power consumption in standby mode, which results in very little discharge of the battery when the vehicle is not in use.

This new technology thus enables the output power of the regulator to be increased to 50A while having excellent voltage regulation. Additional benefits such as reduced heating, high efficiency and advanced electronic control make this new controller the first choice for controlling your vehicle’s battery circuit.
