A new model of bipolar power supplies for LNLS steering magnets using full-bridge topology

This work presents the newest family of steering magnet bipolar current sources developed at LNLS, which will be used to replace the old ones. Unlike previous models, the new 10V/10A power supplies are fully switchmode type. The topology is based on a full-bridge converter using PWM unipolar switching. This paper presents the first results, such as current ripple, stability and time response.
