AC and DC converters are one of the most important components of today\'s electrical and electronic systems, providing the essential power supply for a variety of devices and operations. The CINT1200A2875K01 is one such example, a high-power low-voltage AC/DC converter specifically designed for use in safety-critical applications like medical equipment, aerospace vehicles and industrial machinery. This article will explore the application field and working principle of the CINT1200A2875K01.

The CINT1200A2875K01 is suitable for powering a variety of electronic devices and components such as motors, pumps, sensors, and appliances. It is a versatile and reliable power converter, optimized to provide efficient, reliable and precise power conversion in applications where the frequency and voltage must remain stable. The device operates on AC and DC input voltages from 85 to 264 VAC and from 250 to 450 VDC, with the ability to provide up to 1200W of output power. The built-in short circuit protection makes it a safe and reliable choice for any application.

The CINT1200A2875K01 features power factor correction, enabling it to meet EN 61000-3-2/-3 compliance for harmonic distortion. It is equipped with an integrated resonant boost converter, which provides a constant output voltage independent of the input voltage, reducing noise during start-up and decreasing power loss. In terms of safety, the product complies with the latest safety standards, including UL/EN60950-1, IEC/EN60335-1 and 3262-5. This ensures high reliability and safety in operation.

The CINT1200A2875K01 is based on a Full Bridge Resonant (FBR) topology, which works by controlling the power flow with the help of two halves of an AC wave cycle. When the input voltage increases, the voltage across the start capacitor rises, and the power switch turns on. In this phase, the power flows from the mains AC to the capacitor, creating a positive output voltage across the load. As the input voltage continues to rise, the power switch turns off, allowing the energy stored in the start capacitor to be released through the inductor to the load. This generates a negative output voltage that provides the power required.

In short-circuit or overload conditions, the circuit activates a current limit protection, quickly switching the power switch off to protect the circuit from damage. This makes the CINT1200A2875K01 not only reliable and efficient, but also safe in critical applications.

In conclusion, the CINT1200A2875K01 AC/DC converter is a powerful, reliable and efficient power supply for a variety of high-power applications. It is based on a reliable Full Bridge Resonant topology with built-in safety features, making it suitable for use in safety-critical applications. With EN 61000-3-2/-3 compliance and a wide range of input and output voltages, it is an ideal choice for any system requiring precise and reliable power conversion.
