AC DC Converters

AC DC converters are used for converting alternating current (AC) to direct current (DC) in order to power electronic devices. A practical way to achieve this conversion is through the use of rectifiers, which use semiconductor components such as diodes in order to generate the DC voltage. There are many different types of AC DC converter available, and the type chosen depends on the application.

RWS150B28 Application Field and Working Principle

The RWS150B28 AC DC converter is a powerful, efficient module designed to convert AC main supply voltage into a steady DC voltage. It is particularly suitable for applications such as electric vehicles where a DC output voltage is required. The key benefits of this type of converter are its low EMC interference, robust design and high efficiency. In addition, the module offers current limiting and short-circuit protection ensuring improved safety and reliability.

The RWS150B28 AC DC converter works by using a diode bridge rectifier to convert the incoming AC voltage, typically 230V at 50Hz, to a DC voltage with a ripple of approximately 120mV. The regulated output voltage of the module is then set through a potentiometer located on the AC input side of the module. The output is usually set at the factory, but can be adjusted if the required output voltage is different to the factory setting.

In order to regulate the output, the module has an integrated linear voltage regulator IC which monitors the output and makes necessary voltage corrections. The output current rating of the module is 50A and a fan is included to ensure efficient cooling. The module also contains LED indicators which indicate the presence of AC power and the DC output voltage.

Conclusion

When selecting an AC/DC converter for any application, it is important to choose the right one for the job. The RWS150B28 converter is an excellent choice for electric vehicle applications, offering a robust design, high efficiency, low EMC interference, adjustable output voltage and current limiting capabilities. It is a powerful and reliable AC/DC converter providing a stable DC output for a variety of applications.
