用于线路瞬态改善的具有快速占空比计算控制的CCM非反相Buck-Boost变换器

A continuous-conduction mode (CCM) noninverting buck-boost (NBB) converter with a fast duty-cycle calculation (FDCC) control and duty-cycle locking strategy is proposed in this paper. Utilizing auxiliary and adjustable slopes of the modulation signal, the FDCC control not only rapidly determines an accurate duty cycle but also keeps the compensator output constant when the input voltage changes.
