DC-DC converters are components responsible for the conversion between various DC power supplies. The device being discussed in this paper is AEH10A24N, belonging to the DC DC converter category. This section will cover its application field and working principle.

Application Field

The AEH10A24N is a medium power, DC-DC converter designed for telecommunication and personal mobility applications. It can be used in dozens of scenarios, ranging from battery chargers, power supplies for satellite communications, and power converters for medical devices. It also finds application in robot systems, industrial electronics, and anything in between.

It is quite versatile and can handle input voltage levels ranging from 24 to 40Vdc. Moreover, it is capable of adapting to different levels of power consumption, going up to 25W with a minimum output voltage of 10Vdc. Because of its various features, AEH10A24N is suitable for a wide variety of applications.

Working Principle

The AEH10A24N converter is based on a circuit working in a buck-boost configuration. Essentially, it is a transformer consisting of two coils connected in series, with the input voltage connected to both of them. Switching between the two coils, the device converts the input voltage to the required output voltage. This is known as an inductor-based voltage converter.

Concerning the circuit configuration, the AEH10A24N incorporates a converter based on the switching principle, making it a full-bridge converter. The switching element is composed of a high-side and a low-side MOSFET switch. A pulse-width modulation (PWM) controller is used to control the two switches, thus providing output voltage regulation. In this way, the converter adjusts the output voltage according to the system’s requirements.

Additionally, the circuit configuration includes an overvoltage protection feature that allows the converter to shut down when a critical voltage level is reached. This is a safety device meant to prevent damage to the converter’s components in the event of voltage spikes. It also has an input overvoltage protection feature that limits the maximum voltage allowed at its input.

Conclusion

AEH10A24N is a medium power, DC-DC converter designed for telecommunication and personal mobility applications. Its versatile operation range and wide array of features make it suitable for most scenarios in which it is needed. Its circuit configuration follows the buck-boost principle and contains a full-bridge configuration, a PWM controller, and additional protections.
