Abstract
The present disclosure provides a single- and multi-phase DC/DC converter and a control method thereof that can offer a wide range of voltage conversion ratio by substantially reducing the switching frequency range, thereby resulting in performance improvement. Reduction in the switching frequency range is achieved by controlling the output voltage or current with a combination of variable duty ratio, variable frequency, and delay-time control.
