AC DC Converters

The JWS7515/A is a two-stage AC/DC converter designed for a variety of applications, including variable speed drive systems, soft starters, motor drives and power systems. The series consists of a high-performance, low-noise, fixed frequency AC/DC converter, a high-voltage bi-directional current regulator, and an active filter module, allowing customers to throttle the loads in their systems with precision and reliability.

Performance

The AC/DC converter in the JWS7515/A is rated for up to 75A of output current, with a peak power rating of 18kW. It is designed to provide high efficiency, low noise, and low harmonic generation operation in both linear and switching mode operation. The high voltage bi-directional current regulator can provide up to 80A of output current at 480VAC, and up to 30A of output current at 575VAC. The active filter module comes with built-in signal processing capabilities, providing adjustable voltage and current signal control.

Working Principle

The JWS7515/A works on a two-stage principle. In the first stage, an AC/DC converter converts incoming alternating current into direct current, which is then sent to an active filter module. This module works to reduce any remaining AC component in the direct current signal. Finally, a high voltage bi-directional current regulator converts the direct current back into alternating current, providing precise voltage and current control.

Applications

The JWS7515/A is well-suited for a variety of applications, including variable speed drive systems, soft starters, motor drives, and power systems. Its high-performance, low-noise operation makes it ideal for applications where reliability and precision are critical. Its advanced features, including built-in signal processing capabilities and bi-directional current control, make it an invaluable tool for powering a variety of loads.
