Average current-mode control and charge control for PWM converters
Two control schemes for PWM converters, average current-mode (ACM) control and charge control, are studied in this dissertation. The small-signal models are derived for continuous-conduction mode PWM converters employing these two controls. Sampled-data modeling is applied to the current loop …

Generalized Average-Current-Mode Control of Single-Phase AC-DC Boost Converters with Power Factor Correction
The dissertation presents a generalized average-current-mode control technique (GACMC), which is an extension of the average-current-mode control (ACMC) for single-phase ac-dc boost converters with power factor correction (PFC). Traditional ACMC is generalized in a sense that it offers improved …

Digital control of a multi-channel boundary-conduction-mode boost converter for power-factor-correction applications
This thesis focuses on the design of digital control schemes for multi-channel boundary-conduction-mode (BCM) boost converters. Multi-channel BCM boost converters are commonly used for the front-end power-factor-corrected (PFC) stage of isolated ac-dc power supplies due to the advantages of being …
