The invention provides a household light storage and charging integrated system based on SiC. The household light storage and charging integrated system comprises a direct current charger module, a photovoltaic charger module, a photovoltaic energy storage module, a grid-connected/off-grid inversion module, a battery charging and discharging control module and a grid-connected/off-grid switching module. The functional power conversion realizes the control flow of energy through the three-phase six-switch PFC module, the bidirectional CLLC module and the photovoltaic DCDC circuit; according to the invention, a Bi-DCAC + Bi-DC/DC + magnetic isolation technology is adopted, and the system is platformized; and the system efficiency is improved through the control optimization method.

    本发明提供了一种基于SiC的家庭光储充一体系统,包括直流充电机模块、光伏充电机模块、光伏储能模块、并/离网逆变模块、电池充放电控制模块、并/离网切换模块;其功能功率变换通过三相六开关PFC模块、双向CLLC模块、光伏DCDC电路实现能量的控制流动;本发明采用Bi‑DCAC+Bi‑DC/DC+磁隔离技术,平台化系统;通过控制优化方法提高系统效率。
