面向智能电网光伏与储能系统的高效率双向Buck-Boost变换器

This paper proposes a new bidirectional buck-boost converter, which is a key component in a photovoltaic and energy storage system (ESS). Conventional bidirectional buck-boost converters for ESSs operate in discontinuous conduction mode (DCM) to achieve zero-voltage switching turn-ON for switches. However, operation in DCM causes high ripples in the output voltage and current, as well as low power...
