AC DC Converters are reliable power conversion solutions applied mainly for reducing the voltage from AC main supply to a lower DC voltage. XMS500FR application field and working principle is one of the most widely used AC DC converters in the current power converters’ market.

Application Field

The XMS500FR is mainly applied for low voltage systems, such as household electric equipment, office automation, electronic game, small motors and so on. Because of its extremely wide input voltage range, it can efficiently convert different input AC voltage to a stable DC voltage with less distortion. Of course, by virtue of this superior performance, it can also be found in higher-end applications such as rail, transportation, medical and communication equipment.

Features

The virtually universal input voltage range and maximum efficiency makes this family a small yet efficient choice for most application needing an AC/DC converter. With its compact size and superior efficiency, this converter is specially designed for very small systems with space constraints. This converter is provided with several protection and filtering functions which can provide an effective safeguard for the user and the equipment, such as short circuit protection, over-voltage protection, over-current protection, over-temperature protection, etc.

Working Principle

The common mode noise generated by the XMS500FR is counteracted by placing two coils around the Y-capacitor of the converter’s input circuit. This counter balance is established by the currents passing through the coils which are proportionally related to the common mode noise. Overall, this inverter works by receiving alternating current from the power grid, then stepping down the voltage, rectifying it and finally setting it to the proper DC output voltage and current.

The circuit for the XMS500FR converter utilizes a full bridge rectifier combined with two linear regulators and a switching frequency of 150 kHz. The basic operation of the converter is related from two series of steps that are feedback-controlled, first the voltage is rectified by the full bridge rectifier, after that the filtered AC voltage is fed to the linear voltage regulator which finally sets the output voltage at the desired level.

In conclusion, XMS500FR is a reliable AC/DC converter that provides a low cost solution for AC voltage to DC voltage conversion. These are the most widely used AC DC converters in the current power converter’s market. XMS500FR converter is provided with several protection and filtering functions, and a wide input voltage range making it a small yet efficient choice for most applications.
