Conventional circulating current (CC) control schemes of the modular multilevel converters (MMC) typically suppress CC to zero reduce system loss. However, non-zero can also bring additional benefits. In this paper, a peak arm minimization method MMC using multiple injection (MCCIC) is studied. Specifically, second-order (SOCC) and fourth-order (FOCC) are used achieve purpose. Firstly, amplitud...

the first step in the prenatal diagnosis of x-linked genetic disorders is determining fetus gender. current invasive methods to obtain the dna source of the fetus instead of its miscarriage risk, has harmful stress for high risk pregnancies. cell free fetal dna (cffdna) circulating in the maternal blood, has now become a useful source of noninvasive prenatal diagnosis. considering limitation of...
