Working Principle
FFSH10120ADN-F155 rectifier array operates when fitted to an electrical circuit. The 4 diodes in the array can be forward-conducting type (1st diode) or reverse-blocking types (next 3 diodes). A single rectifier can be biased one way to achieve a rectifying action. The rectifying action is limited by the two diodes being on different sides of the circuit. This can be seen in the case of a DC motor or an electric generator, where when the current is reversed, the electric field is reversed, forcing the rectifying diodes to conduct in the reversed direction.
When fitted to a switched mode power supply, the FFSH10120ADN-F155 rectifier array acts as a voltage regulator, keeping the voltage stable within the output of the device, regardless of input load variation. By controlling the forward diode, the array modulates the output voltage by regulating the amount of current that passes through it. This helps to ensure a constant voltage at the output.
The FFSH10120ADN-F155 rectifier array is also used in photovoltaic systems, where it works as a battery charging system by using DC current. The 4 diodes act as a bridge between the power supply and the battery, allowing only one way current flow. This helps to improve the efficiency of the solar panel while charging the battery.
Conclusion
FFSH10120ADN-F155 is a diode rectifier array that is used in many applications, such as automotive, on-board or vehicle supplies, DC/DC converters, general purpose inverters, switched mode power supplies and high frequency power supplies, among others. The device works by fitting it to an electrical circuit and it functions as a voltage regulator. It can also be used for battery charging in photovoltaic systems by acting as a bridge between the power supply and the battery.
