Abstract
Boost and flyback converters have a right-half-plane zero in their control-to-output transfer function. This property makes the controller difficult to be designed with the classical frequency-domain approach to ensure good output regulation and fast response over wide frequency bandwidth of input voltage and output load perturbations. Instead of a small-signal design approach, this paper presents a cycle-by-cycle state trajectory prediction (STP) control method for boost converters. The method is based on predicting the output voltage after a hypothesized switching action. The output can revert to steady state in two switching actions under large-signal input voltage and output load disturbances. Theoretical predictions are verified with experimental results of a 120W 18/24V prototype.
