Abstract

Sensorless current-mode (SCM) control of dc-dc converters is a feed forward open loop scheme, which is compared to peak current-mode (PCM) control. Small signal model simulations of each controller are validated by experimental results. SCM offers improvement over the line disturbance rejection of current-mode control without feedback or current sensing. SCM is demonstrated to be useful in both open loop and closed loop configurations, by exploiting its inherent reference tracking and line disturbance rejection. In contrast, PCM requires high gain two-loop control for voltage regulation.
