DC DC Converters

DC DC converters are electronic devices that convert direct current (DC) from one voltage level to another, typically converting low-voltage DC to higher-voltage DC. The TEP 75-7215WI-CMF is a type of non-isolated flyback converter, specifically designed to provide adjustable output voltage with a power factor corrector for high performance applications.

Application Field

The TEP 75-7215WI-CMF features a wide range of applications in the power distribution, telecommunication, automotive, and industrial sectors, notably in the following areas:

• Battery chargers
• Main power supply units for telecom, military, and general electronic equipment
• DC/DC Electronic Power Modules
• Industrial Robotics
• Automotive E-Mobility Components

Working Principle

The operation of the TEP 75-7215WI-CMF is based on the principle of a Flyback converter topology. This type of converter utilizes the action of an inductor to store energy in the form of a magnetic field. When a switch is closed, current begins to flow through the primary winding of the inductor, while the other end of the winding is connected to the ground. The current through the primary winding stores energy in the form of a magnetic field.

When the switch is opened, the magnetic field created by the current in the primary winding collapses and induces a voltage in the secondary winding of the inductor. This voltage is then rectified and filtered to obtain a dc output voltage. The output voltage level is regulated using a feedback loop that adjusts the duty cycle of the input switch. This allows for precise output voltage control.

The primary advantage of a Flyback converter is its ability to provide galvanic isolation between the input voltage and the output voltage. This is important when dealing with high voltage power sources that must be kept isolated from sensitive electronic loads. Furthermore, the Flyback converter is simple in structure, making it cost-effective and easier to implement when compared to other types of power converters.

Conclusion

The TEP 75-7215WI-CMF is a versatile and cost-effective non-isolated Flyback converter designed for a range of applications. As a switching power supply, it provides adjustable output voltage to power devices with high performance, as well as offering galvanic isolation between the input and output voltages.
