本文研究了多相飞跨电容多电平（FCML）变换器与耦合电感的涟漪减少和本征飞跨电容电压平衡。FCML拓扑和耦合电感是两种常用的技术，以减少电源转换应力，减少涟漪电流，并提高系统性能。将耦合电感器与多相FCML转换器相结合提供了广泛的设计机会。所示的耦合电感器本质上平衡飞跨电容器电压，授予更大的鲁棒性相比，非耦合电感器和自然平衡的干扰。耦合电感和FCML结构提供的涟漪减少。理论推导的实验验证使用两相，三电平FCML转换器。只要电感器充分耦合，就可以实现涟漪减小和电压平衡。
This paper investigates multiphase flying capacitor multilevel (FCML) converters with coupled inductors for ripple reduction and intrinsic flying capacitor voltage balancing. FCML topologies and coupled inductors are two commonly used techniques to reduce power conversion stress, reduce ripple current, and improve system performance. Combining coupled inductors with multiphase FCML converters opens a wide range of design opportunities. The coupled inductors are shown to intrinsically balance the flying capacitor voltages, granting greater robustness to disturbances compared to uncoupled inductors and natural balancing. The ripple reduction offered by the coupled inductors and FCML structure are derived. The theoretical derivations are experimentally verified using a two-phase, three-level FCML converter. The ripple reduction and voltage balancing are realized as long as the inductors are sufficiently coupled.
