AC DC Converters

AC/DC converters are widely used in power systems and electronic devices to convert alternating current (AC) to direct current (DC). The PBA75F-24-RN is a single stage, AC/DC converter that is able to convert a single phase, or three phase, input voltage to a regulated DC output. The converter features robust power control and a wide input range, enabling it to provide a high quality DC output voltage in various applications.

Applications

The PBA75F-24-RN is mostly used for low power applications such as solar and wind power systems and small industrial electronics. The converter’s wide input range and low power consumption ensures that it is suitable for use in applications where reliable and efficient power supply is needed. Moreover, due to its small form factor, it can be used in applications where space is a constraint, such as in automotive, military, and communication systems.

Features

This converter features a wide input range, which can accept inputs of 100VAC to 375VAC and 50/60Hz and offers several features to maximize its efficiency and power capacity. The main features of the PBA75F-24-RN are PFC (Power Factor Correction) capability to reduce THD (Total Harmonic Distortion) on the output, adjustable output voltage, over-voltage and under-voltage protection, short circuit protection, isolated base plate, built-in EMC filter, short circuit proof and resonant soft switching design.

Working Principle

The PBA75F-24-RN works by using a combination of power electronic switching and control systems to provide a highly efficient and reliable AC/DC conversion. The input side utilizes a full-bridge rectifier to convert the AC input into a DC voltage. The rectified voltage is then fed to a resonant LLC DC-DC converter. The LLC converter produces high frequency, high voltage, low current square waves that are passed through an output transformer. The transformer then reduces the voltage to the required output voltage. The DC output is then filtered and regulated using a control system to ensure the output voltage is stable and within the required limits.

Conclusion

The PBA75F-24-RN is a single stage, AC/DC converter that provides a robust, adjustable, and efficient power conversion solution for small industrial, solar, and wind power systems. Its wide input range and excellent features enable it to produce an excellent and reliable DC output voltage in a variety of applications. The converter is powered by a combination of switching and a resonant LLC DC-DC converter to provide high efficiency and accurate output voltage regulation.
