AC DC Converters are widely used in various industrial applications. This is due to their ability to convert alternating current (AC) into direct current (DC). The LPS252-C is an example of such a converter. In this article, we will discuss its application field and working principle.

Application Field

The LPS252-C is designed for use in applications requiring Upto-240V DC, such as LED lighting, solar panel photovoltaic systems, backup power systems, and industrial control systems. It can also be used in medical applications such as X-ray, magnetic resonance imaging (MRI), medical imaging, and medical electronic equipment.

The LPS252-C is a highly efficient and reliable AC DC converter that is capable of providing up to 240V DC output for a wide range of input voltage ranges, from 90V to 260VDC. It provides an excellent power factor (PF) of up to 0.96, as well as low total harmonic distortion (THD) of less than 0.5%. This makes it well suited for various commercial and industrial applications.

Working Principle

The LPS252-C is a two-stage linear AC DC converter featuring a power factor correction (PFC) stage followed by an isolated DC/DC stage. The first stage, the power factor correction stage, rectifies the input AC power and controls the current drawn from the AC mains such that the input power factor is always close to 1. This reduces the amount of power wasted by the system and improves the overall efficiency.

The second stage, the isolated DC/DC stage, rectifies the PFC stage output and converts it into the desired DC output voltage. The DC/DC stage is further divided into a buck converter and a boost converter. The dc/dc stage can be configured to output either a constant voltage or a constant current. This allows the user to accurately regulate the output voltage and current to meet the requirements of the application.

Conclusion

In conclusion, the LPS252-C is a highly efficient and reliable AC DC converter that is capable of providing up to 240V DC output for a wide range of input voltage ranges. It features both power factor correction and an isolated dc/dc stage to ensure high power conversion efficiency. The LPS252-C is ideal for use in LED lighting, solar panel photovoltaic systems, backup power systems, industrial control systems, and medical applications.
