摘要

在负载点(POL)应用中，多相串联电容降压(SCB)变换器是一种有吸引力的候选稳压模块(VRM)。但是，要实现对SCB变换器的快速暂态要求，还需要对控制问题和技术进行更多的探讨。本文讨论了采用相位重叠暂态改进控制时SCB变换器中的电压应力和振荡问题。为了在保持器件电压应力和避免飞电容电压振荡的情况下，获得良好的暂态性能，提出了一种实现简单的部分相位重叠暂态控制方法。仿真和实验结果表明了该控制方法的有效性。

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.
