AC DC Converters

The GWS25048 is a three-phase AC-DC converter designed for operation up to 500V DC and is the only three-phase converter that meets the requirements for both AC and DC inputs. It offers an adjustable output voltage, extremely low output voltage ripple and extensive protection features. Its wide range of applications include industrial and transportation loads, distributed energy technology and automated manufacturing plants.

The GWS25048 provides a single stage conversion from AC voltage to DC output voltage. It utilizes a full-bridge rectifier to rectify the AC voltage to a DC voltage. Depending on the type of AC-DC converter you decide to use, the rectifier circuitry can be made up of either three-phase or single-phase rectifier elements. The single stage conversion provides a simple design but can cause substantial output voltage ripple and potential current imbalances in three-phase AC-DC conversion systems. To manage both of these effects, the GWS25048 has an innovative current-ripple regulation feature, which provides smooth DC output current and reduces voltage ripple. This feature is especially useful in applications that are sensitive to voltage or current fluctuations.

The GWS25048 also features an adjustable output voltage feature that allows for a precise control of the output voltage. This feature is best used in applications where the input is not consistent and output voltage may need to be adjusted correspondingly. Another important protection feature available with the GWS25048 is overload protection. When the output current exceeds a preset value, the converter automatically shuts off and does not resume operation until manually reset.

The core of the GWS25048’s flexibility lies in its control circuit, which consists of a microprocessor, connectors for external control and data static memory and protection circuits. This control circuit can be tailored to suit the specific needs of the customer\'s application, whether it uses a microprocessor interface, an analog circuit, or an open-loop control system. The GWS25048 provides a number of parameters to control the output voltage, current, ripple and other performance characteristics.

The GWS25048 is designed to provide high performance with reliable operation, making it suitable for applications requiring precise control and constant current or voltage. With its extensive protection features, low output voltage ripple and adjustable output voltage, the GWS25048 is an ideal choice for challenging applications such as industrial and transportation modules, distributed energy technology and automated manufacturing plants.
