AC DC Converters

AC-DC converters are electrical devices that convert alternating current (AC) signals into direct current (DC) signals. The DC output may have either a fixed or a variable voltage or current, depending on the application. In this article, we will discuss the application field and working principle of the RAC10-24SK/277 AC-DC converter. The RAC10-24SK/277 is designed for industrial and commercial applications where a three-phase AC supply is available. It is a 3-phase bridge rectifier with a power rating of 10A at 24V, supplied in a DIN-rail mountable housing. The converter is optimized for switching power supply applications with an input voltage ranging from 385 to 450 VAC and an output voltage of 24 VDC. As an AC-DC converter, the RAC10-24SK/277 allows users to benefit from an efficient, high-performance AC-DC conversion. The converter employs a pulse width modulation (PWM) rectification circuit that provides a constant output current, regardless of the input voltage fluctuations. The PWM control technique enables the converter to deliver a steady output voltage with a low ripple, resulting in minimized potential noise and interference levels. The controller of the RAC10-24SK/277 is composed of two parts: an opto-isolated voltage triggering circuit and an open loop switching controller. The opto-isolated triggering circuit imparts the necessary timing information and switching angles. The controller is responsible for maintaining the steady output voltage with the help of the converter feedback information. The converter also features integrated protection circuits which ensure safe operations in case of overload or surge. It includes an overcurrent protection circuit which disconnects the load from the input power supply if the converter current exceeds the maximum output current rating. If the voltage spikes or falls below the specified voltage level, the overvoltage and undervoltage protection circuits will cut off the input power supply to the load. In a nutshell, the RAC10-24SK/277 is a 3-phase bridge rectifier with an output rating of 10A at 24V. It features PWM circuit control and integrated protection circuits to provide safe and efficient AC-DC conversion with minimal voltage ripple. The converter has various applications in commercial and industrial settings.
