  • Abstract
    This work presents a general analysis framework for control loop design of two-stage converters. The results yield a thorough explanation of various loop design approaches. A three-loop method to extend the system bandwidth is proposed. The new control design algorithm is applied to a 48 V/3.3 V two-stage converter. Experiments verify the effectiveness of the control loop design approach.
