Photovoltaic converter with uninterruptible power intelligent commutation function and working method thereof

The invention discloses a photovoltaic converter with an uninterruptible power intelligent commutation function and a working method thereof. The photovoltaic converter aims at solving the problem that a low-voltage power distribution network is usually accompanied by three-phase imbalance, and the three-phase imbalance problem of the low-voltage power distribution network is more prominent along with distributed photovoltaic large-scale access. In order to alleviate the problem of three-phase imbalance caused by distributed photovoltaic aggravation, uninterruptible power commutation is carried out on distributed single-phase photovoltaic output power at a source side, so that transfer of single-phase photovoltaic grid-connected power in a low-voltage power distribution network is realized, and the three-phase imbalance degree of the low-voltage power distribution network is obviously alleviated. 本发明公开了一种具有不断电智能换相功能的光伏变换器及其工作方法包括：本发明针对低压配电网通常伴随着三相不平衡问题，且随着分布式光伏大规模接入，低压配电网三相不平衡问题更加突出，为减缓分布式光伏加剧造成的三相不平衡问题，本发明在源
