JWS7548/C

AC DC converters are essential components in modern electronic systems where they are used to provide a regulated, stabilized DC power supply. The JWS7548/C is a type of AC DC converter that utilizes a variable-frequency approach to produce a constant, regulated DC voltage output. This AC-DC converter features robustness and scalability, making it suitable for a variety of applications.

The JWS7548/C is a fully integrated switch power supply module with a universal AC input. It converts input voltage ranges from 85 volts to 265 volts AC (50Hz-60Hz) with a regulated DC output rated at 48v at 12A (576W). The design features high reliability and integration, which makes it suitable for power applications requiring high efficiency, low losses, and high current capabilities.

The JWS7548/C utilizes a variable frequency technique to produce a stable DC output voltage. This technique involves using an extremely-high-speed power factor correction (PFC) controller to reduce the rectified input voltage ripple. The PFC then drives the primary power stages, a group of high-speed IGBTs and diodes. A resonant half-bridge topology is used to step up the AC voltage, and an advanced isolated voltage controller is used to control the DC output.

The JWS7548/C is perfect for applications requiring high-performance power delivery and the ability to produce clean and stable DC supplies, such as industrial control systems, motor drives, and renewable energy systems. Due to its small size and high power density, this device is ideal for applications with limited space for components.

The JWS7548/C AC DC converter provides exceptional efficiency, with a typical efficiency of 92% at full load and up to 96% at low load. This high efficiency translates into cooler operation and extended system lifetime. The ability to operate over wide range of temperatures and input voltages ensures consistent performance even in challenging environments. Furthermore, the JWS7548/C has a working frequency of 80khz, making it suitable for higher power applications.

The JWS7548/C is also a very reliable device as it features numerous protections such as temperature protection, short circuit protection, and over-voltage protection. This ensures the safety of the internal components and reduces the chances of system damages in the event of varying load conditions.

In summary, the JWS7548/C AC DC converter is a reliable and high-performance device suitable for a range of power applications. Its universal AC input, high efficiency, and numerous protection features make it an essential component for applications requiring high power density and limited space.
