Partial Phase Overlap Control for Multiphase Series Capacitor Buck Converter
The multiphase series capacitor buck (SCB) converter is an attractive candidate voltage regulator module (VRM) in point-of-load (POL) applications. However, there needs to be more discussion on the control issue and technique to achieve the fast-transient requirement for the SCB converter. This paper discusses the voltage stress and oscillation issue in the SCB converter when applying the phase overlap transient improvement control. A partial phase overlap transient control with simple implementation is proposed to achieve good transient performance while maintaining the device voltage stress and avoiding flying capacitor voltage oscillation. The simulation and experimental results under load step-up transient show the effectiveness of the proposed control.
期刊介绍：
COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
