DC DC Converters: SFS15482R5C Application Field and Working Principle

DC DC Converters are electrical circuits or electromechanical devices used to convert electric power from one DC voltage level to others. SFS15482R5C is a microprocessor-controlled DC DC converter, which is suitable for hard-switching applications.

Application Field of SFS15482R5C

Primarily, SFS15482R5C is used in high power or power-conversion applications. The output range can reach 8.6kW, 100A and 500Vdc. It can convert a wide source voltage range from 20Vdc to 175Vdc. In addition, it is characterized by high efficiency, up to 93%, and low output noise. Therefore, SFS15482R5C is suitable for high-end applications such as motor drives, telecom systems, and lighting/audio-video systems.

Working Principle of SFS15482R5C

The working principle of SFS15482R5C mainly includes the following components: gate drive and voltage regulation. The gate drive is used to control low power or high power switches and is usually implemented with a microprocessor. When the gate drive switch is turned on, it controls the voltage of the power source, allowing it to rise or fall as indicated by the voltage requirement. The voltage regulation is then used to further control the output voltage, ensuring that it stays within a specific range.

In addition, the SFS15482R5C also includes input under-voltage lockout, over-temperatureprotection, and other safety measures. These measures protect the circuitry from damage or over-voltage, preventing potential damage to the load or system.

Apart from the standard features, SFS15482R5C also has adequate protection logic for abnormal situations in order to avoid damage to the system. For example, when the voltage exceeds the set value, it can automatically shut down the switch and restart it after the problem is resolved. Moreover, it also includes pulse-by-pulse current limiting and power limiting circuits.

Conclusion

SFS15482R5C is a microprocessor-controlled DC DC converter that is widely used in high-power applications. It has high efficiency, up to 93%, and a wide input voltage range that can reach up to 175Vdc. The working principle of SFS15482R5C includes gate drive and voltage regulation, and it has adequate protection for abnormal situations, such as over-voltage and over temperature. Therefore, SFS15482R5C is an ideal choice for applications such as motor drives, telecom systems, and lighting/audio video systems.
