Title
Using cross regulation in single-switch single-inductor dual-output CCM boost converter to simplify controller design
Abstract
Cross regulation of single-inductor multiple-output (SIMO) boost dc/dc converter is usually considered as a key factor that degrades the voltage regulation of individual outputs. Analysis of the cross coupling of a single-switch single-input dual-output (SIDO) boost converter operating in continuous conduction mode (CCM) reveals that it is an automatic current feedback mechanism during converter operation, which, however, can improve steady-state voltage regulation of both outputs. It is possible to use this natural cause to simplify the PWM controller design. That is, only one output needs to be sensed and regulated. The other output will be regulated accordingly. The drawback is the transient response of one output will share by another output Low-frequency model of a SIDO boost converter is derived and analyzed to reveal such phenomenon. A single Type-III PWM controller is designed for one of the outputs but is able obtain both regulated outputs. The analysis and design are verified by both simulation and experimental results.
