Abstract :
Voltage feedback loops for AC/DC switch-mode magnet power supplies are designed and analyzed. In order to achieve low-ripple fast-response voltage loop performance, proper structures of feedback controllers and output filters are identified. In addition, feedback loop stability is analyzed, and the safe operation region of the system is determined, taking into account the nonlinearity of the pulse-width modulator. Results from an experimental breadboard are provided for verification
