Regulator/rectifier Mosfet for Polaris Motorcycle 2009-2014

Description

This new technology has renewed the concept of three-phase ladder controllers. For many years, these devices used silicon-controlled rectifiers (SCRs) to drive excess energy from the generator to ground, keeping the battery voltage constant.

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

The demand for power in modern motorcycles and ATVs is increasing today by the use of additional electronic modules such as injection system, high-efficiency lighting, numerous accessories, etc. more and more. This means a large amount of energy coming from the generator and the SCR shunt regulator will not be able to control it.

The main reason is the low energy efficiency, the internal losses of the controller lead to overheating and premature damage when currents greater than 35A are routed through the controller. 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 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 forward voltage drop (about 1.5V @ 35A) as it works like a power diode. When the current increases, the power loss (eg heat) increases in parallel.

LOSS OF POWER UNIT (W) = TRIP CURRENT (A) X VOLTAGE LOSS (V)

Advantages:

– 3-PHASE SHUNT CONTROLLER WITH HIGH ENERGY EFFICIENCY

– OUTPUT POWER UP TO 50A

– PRECISE ELECTRONIC CONTROL OF THE BATTERY VOLTAGE PREVENTS IGNITION USER

– LOWER HEAT DEVELOPMENT LEADS TO HIGHER LIFE

– LOW-POWER STANDBY MODE IF VEHICLE IS NOT USED

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

In use, they behave like a low-rated high-current resistor that conducts all the excess current of the generator into the 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 life of the controller.

MOSFET technology has been continuously improved in recent years due to its wide application in consumer and industrial electronics. Semiconductor integration technology offers higher load capacity in reduced space 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 the output current flows through them, they must offer both great ruggedness and stability, as well as efficient current control. Our MOSFET regulators use high-current rectifier diodes with extremely low voltage drops, which help prevent overheating and meet the aforementioned requirements.

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

This new technology allows the output power of the regulator to be increased up to 50A while maintaining excellent voltage regulation. Additional benefits such as reduced heating, high efficiency and advanced electronic control make this new controller the first choice to control the battery cycle of your vehicle.
