DC-DC converters are becoming increasingly prevalent in both residential and commercial settings. The REC3-2409DRWZ/H6/A/SMD is a type of efficient, high-voltage, bipolar switching DC-DC converter, developed to address the need for higher-current devices and tighter regulation in a wide range of applications. This article will discuss the application field and working principle of the REC3-2409DRWZ/H6/A/SMD.

Applications

The REC3-2409DRWZ/H6/A/SMD is designed for use in higher-current applications, such as industrial motor control circuits, robotics, remote sensing and communications, high-efficiency lighting systems, as well as automotive, rail and avionic power systems. In addition, its high-voltage nature makes it suitable for use in harsh environments (e.g. oil and gas refineries, or medical and aerospace applications).

Working Principle

The REC3-2409DRWZ/H6/A/SMD is comprised of two insulated-gate bipolar transistors (IGBTs), each of which operates as the primary side of a transformer. Each IGBT’s conduction state is determined by the duty cycle of an onboard pulse width modulated (PWM) regulator.When the PWM is turned on, the rising voltage at the output of the PWM causes the IGBT to turn on. As a result, current passes through the primary winding of the transformer, inducing a voltage in the secondary winding. This voltage is further multiplied by the turns ratio of the transformer, allowing higher voltages to be obtained at the output. When the PWM is off, the IGBT switches off, allowing the current in the transformer’s primary winding to collapse. This reduces the voltage in the secondary winding, while dissipating stored energy in the inductance of the primary winding. This switching action is repeated at a high frequency, resulting in a continuous output voltage.

Conclusion

The REC3-2409DRWZ/H6/A/SMD is a high-voltage, bipolar switching DC-DC converter which is designed for use in high-current applications. Its efficient and tightly regulated operation makes it suitable for use in a variety of industrial, automotive, rail and avionic power systems. Furthermore, its efficient and tightly regulated operation is made possible by its use of two IGBTs which are each switched on and off by a PWM circuit.
