REC3-2415DRW/H4/A

DC-DC converters are electronic circuits which transform power available from a DC source to another with the desired characteristics. The REC3-2415DRW/H4/A is a non-isolated step-down DC-DC converter which reduces AC to the desired DC voltage. Its application field and working principle are described in detail in this article.

REC3-2415DRW/H4/A Application Field

The REC3-2415DRW/H4/A is designed to be used in a wide range of applications. It is particularly suitable for:

• Powering low voltage DC circuit boards for automotive electrical systems. These boards are usually powered by AC/DC power supplies.
• Driving low power DC motors.
• Powers LED lighting systems.
• Actuators for controlling robotic arms.

The REC3-2415DRW/H4/A can also be used in other applications like UPS systems, power supply systems, and renewable energy systems.

Working Principle

The REC3-2415DRW/H4/A uses a buck topology to convert AC into DC. The main advantage of the buck topology is that it can reduce voltage from a higher level to a much lower level efficiently. This makes it ideal for applications where a fixed output voltage is desired. The basic principle of operation of the REC3-2415DRW/H4/A is as follows:

• The AC voltage is connected to the REC3-2415DRW/H4/A input terminals.
• A MOSFET switch is opened and closed in a repeating pattern or frequency, controlled by the PWM (pulse width modulation) signal. The input voltage is charged to a capacitor whose output is connected to the load.
• The MOSFET switch is closed for a specific amount of time and the voltage on the output capacitor is increased. When the MOSFET switch is open, the capacitor is discharged, thus increasing and decreasing the voltage on the output terminals. This is used to achieve the desired output voltage.

The output of the REC3-2415DRW/H4/A is regulated by the controller which adjusts the duty cycle and frequency of the switching waveform.

Conclusion

The REC3-2415DRW/H4/A non-isolated step-down DC-DC converter is suitable for a wide range of applications including powering low voltage DC boards, driving low power DC motors, LED lighting systems, and robotic arms. It is based on the buck converter topology and works on the principle of charging and discharging of a capacitor. This converter is highly efficient and cost-effective.
