DC DC Converters

DC-DC converters are devices used to efficiently convert a DC input power to a different DC voltage output. They are commonly seen in consumer electronics, automobiles, and other applications requiring the conversion of power from one voltage level to another. The THM 3-2412 is a high power DC-DC converter specifically designed for automotive applications.

Function

The THM 3-2412 is a DC-DC converter that takes in a wide input range of 6V to 24V DC and can deliver an adjustable output of 9V to 28V DC at a maximum current of 100A. This makes it an ideal device for automotive applications where the input power can widely vary depending on the engine running state. The converter includes a maximum power point tracking (MPPMT) function, which helps optimize the converter’s efficiency while staying within the input voltage range.

Design

The THM 3-2412 is designed with a great deal of emphasis on safety and reliability. It includes a built-in over-voltage protection and over-temperature protection functions, as well as an under-voltage lockout feature for preventing battery drain. The device also features a system sleep mode that can be activated to save power while the engine is not running.

Operation

The THM 3-2412 operates using a synchronous buck-converter topology, which utilizes two switches to control the conversion of power from one voltage to another. The switches are controlled by a high-speed control loop that constantly monitors the input voltage level and adjusts the output to match the required level. The MCPPMT algorithm is used to optimize the converter’s efficiency while maintaining maximum power output within the range of the input voltage.

Applications

The THM 3-2412 is commonly used in automotive applications such as the powering of electric vehicle charging systems, on-vehicle power supply, and battery charge and discharge systems. It is also suitable for applications requiring the conversion of AC power to DC, such as in industrial and medical systems.

Conclusion

The THM 3-2412 is a high power DC-DC converter specifically designed for automotive applications. It offers an adjustable output of 9V to 28V DC at a maximum current of 100A and a wide input range of 6V to 24V DC. The converter includes a maximum power point tracking (MPPMT) function, built-in over-voltage protection and over-temperature protection, as well as an under-voltage lockout feature. It is commonly used in applications such as electric vehicle charging systems, on-vehicle power supply, and battery charge and discharge systems.
