DC DC Converters

DC-DC converters are electrical circuits that form a bridge between devices powered by DC (direct current) power sources, such as battery packs, and devices powered by AC (alternating current) power sources, such as wall outlets. Often, the power converter is used to control the voltage between the two sources. Over the past few decades, DC-DC converters have become more complex due to their increasing use in a variety of applications.

Suc10243R3C-G Application Field and Working Principle

The Suc10243R3C-G is a three-phase unregulated DC-DC converter designed to deliver up to 150 watts of output power from an input voltage range of 17V to 75V. It has been developed for a wide range of applications, such as laptops, cellular phones, and other portable devices. The Suc10243R3C-G has a high level of protection against short-circuit, over-current and over-temperature conditions.

The Suc10243R3C-G converter operates by converting an input of direct current (DC) into an output of alternating current (AC). It does this by using a series of transistors and inductors (coils) to transform the input current into pulses. These pulses are then using a rectifier-like bridge circuit before being further filtered and smoothed to generate the output voltage. The pulses are then fed into a set of transformers which convert the AC to DC and regulate the output voltage.

The output of the Suc10243R3C-G is regulated through the use of a feedback loop that samples the output voltage and adjusts the frequency of the pulses outputted by the transistor-based circuitry to maintain a stable output voltage. The pulse frequency can be adjusted through the use of an external potentiometer. This allows the user to adjust the output voltage in order to match the voltage requirements of the device being powered.

The circuit design of the Suc10243R3C-G allows for a high level of efficiency with minimal power loss. It has a power conversion efficiency up to 98.4%. This allows the converter to meet the requirements of energy savings regulations in many countries such as California and Japan.

The Suc10243R3C-G also has a low EMS (electro-magnetic disturbance) level, making it suitable for medical and military applications. It also has high resistance to shock and vibration, making it a reliable choice for use in harsh environments.

In conclusion, the Suc10243R3C-G is a robust and efficient DC-DC converter designed for use in a wide range of applications. With a wide input voltage range, high efficiency, low electromagnetic disturbance and high resistance to shock and vibration, the Suc10243R3C-G has proven to be a reliable and cost-effective solution for many demanding applications.
