摘要

光伏(PV)装置适合住宅环境，发电模式遵循白天住宅用电量的分布。在发电和需求不平衡的情况下，智能光伏通过其电池存储可以吸收或注入电力来平衡它。由于系统成本高，且功率需要经过两次处理，因此需要高效的双向变换器。采用CoolMOS和SiC二极管设计并构建了1.5kW的原型机，在200 kHz硬开关下获得了95%的效率。

High efficient bidirectional battery converter for residential PV systems

Photovoltaic (PV) installation is suited for the residential environment and the generation pattern follows the distribution of residential power consumption in daylight hours. In the cases of unbalance between generation and demand, the Smart PV with its battery storage can absorb or inject the power to balance it. High efficient bidirectional converter for the battery storage is required due high system cost and because the power is processed twice. A 1.5kW prototype is designed and built with CoolMOS and SiC diodes, >;95% efficiency has been obtained with 200 kHz hard switching.
