regulator / rectifier MOSFET 700.27.56

Regulator/rectifier with MOSFET technology

Spare part in original quality

This new technology has innovated the concept of three-phase stepper regulators. For many years these devices used Silicon Controlled Rectifiers (SCRs) to direct excess power from the alternator to ground in order to maintain constant battery voltage.

This was generally accepted and proved to be suitable for small to medium alternators in internal combustion engines. However, newer MOSFET-based regulator technology is becoming more and more popular due to its better performance and many other interesting advantages over SCRs.

Today, the power demand on modern motorcycles and ATVs is increasing more and more due to the use of additional electronic modules, such as fuel injection system, high-efficiency lighting, numerous accessories, etc. This means a lot of power is used from the motor. This means a lot of power coming out of the generator and the SCR shunt regulator is not able to regulate it yet.

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

To solve this problem mentioned above, 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 (about 1.5V @ 35A), because it works as a power diode. If the current increases now, the power loss (eg heat) increases in parallel.



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



Advantage:

- HIGH ENERGY EFFICIENCY THREE-PHASE SHUNT CONTROLLER.

- OUTPUT POWER UP TO 50A

- PRECISE ELECTRONIC CONTROL OF BATTERY VOLTAGE PREVENTS MISFIRING

- LESS HEAT GENERATION ALLOWS A LONGER LIFETIME

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



Unlike other transistors, MOSFET transistors can be characterized as voltage controlled switches, since a completely different semiconductor architecture makes them more energy efficient.

When used, they behave like a low power resistor for high currents, conducting all excess current from the generator to ground. As a result, the voltage drop is very low (less than +/-0.2V at 35A) and power dissipation is drastically reduced. This has a direct impact on less heating of the device and a longer duration of the regulator.

MOSFET technology has continuously improved in recent years due to its wide application in consumer and industrial electronics. Semiconductor integration technology offers increased power handling in a small footprint with excellent efficiency. In addition, they allow faster switching, greater reliability and better control under high voltage conditions.

The power of the rectifier diode is another important factor when it comes to power dissipation. Since all the output current flows through them, they must provide both great robustness and stability, as well as efficient current control. Our MOSFET regulators use high current rectifier diodes with extremely low voltage drop, helping to prevent overheating and meeting the requirements mentioned above.

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

Thus, this new technology allows the output power of the regulator to be increased up to 50 A, while achieving excellent voltage regulation. Additional advantages such as reduced heating, high efficiency and advanced electronic control make this new regulator the first choice for monitoring your vehicle's battery circuit.
