H6-inveter
提出一种新颖的高效率六开关逆变器(H6)拓扑,解决了无变压器单相光伏并网逆变器漏电流问题。 仿真与实验验证了该拓扑具有低共模电压、高质量的并网波形和高效率特征(This paper proposed a novel, high efficiency, transformerless single phase photovoltaic grid-connected inverter with six active switches that alleviate leakage current
issue. This topology embeds two unidirectional freewheel units
into the midpoint of a full bridge inverter, which provide novel freewheel paths and separate battery cells a grid during freewheeling time. )

Real-time-detection-of-negative
同相牵引供电系统旨在实现电能质量的综合补偿。提出了一种基于同步坐标变换的电流检测方法,能实时准确地检测
出负载电流的基波正序有功分量、基波正序无功分量、基波负序分量以及谐波分量,为综合补偿提供了基础。电能质量的补
偿力度与设备容量之间存在非线性关系。提出补偿度的概念,并给出补偿度与电能质量参数的关系,通过给定电能质量期望
参数,实时调整负序、谐波以及无功补偿度,使得综合潮流控制器容量在各电能质量补偿参数之间得到实时优化配置,从而
实现同相供电系统容量优化满意补偿。理论推导和仿真结果验证了所提方法的正确性和可行性。(The cophase traction power supply system aims at achieving power quality comprehensive compensation.A current
detection method based on synchronous reference frame transformation is proposed.The method can decompose the load current
real-timely into fundamental positive-sequence active component,fundamental positive-sequence reactive component,fundamental
negative-sequence component and harmonic component,which lays a foundation for comprehensive compensation.There are
nonlinear relation between compensation strength of power quality and device capacity.The paper proposes the concept of
compensation degree and gives the relationship between compensation degree and power quality parameters.By giving expected
power quality parameters,it adjusts compensation ratios of negative,reactive and harmonics instantaneously,so that the IPFC
capacity can be allocated between power quality compensating parameters optimally and real-timely,thus achieving capacity optimal
satisfactory compensa)
