Abstract :
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.
