摘要：A power converter topology operates as a switching capacitor (capacitivevoltage divider) converter during a first, preferably short portion of a switching cycle toprovide excellent dynamic transient response and as a pulse width modulated converterduring a second portion of a switching cycle to provide flexibility of voltage regulation

and generality of application. This topology can be made self-driven and is capable ofzero voltage switching. Therefore the power converter can be used as one of a pluralityof branches of a multi-phase converter to enhance transient response. The respectivebranches can also be independently optimized for particular load levels and can beoperated independently in a phase shedding manner to improve efficiency at low load.Further, the power converter or respective branches of a multi-phase power converterare compatible with non-linear control to further improve dynamic response.
