一种用于光伏系统的新型双输入高增益无变压器多电平单相微型逆变器

This article proposes a novel single-phase microinverter that is fit to process the power of two photovoltaic (PV) modules in a modular way. The proposed topology combines a full-bridge inverter integrated with two dc-dc boost converters, in addition to a dc link that consists of switched capacitor (SC) networks. The operating modes of the proposed topology are illustrated. The voltage stress of a...
