A feature of this topology is the significant second harmonic component of the current that circulates among the phase legs and mainly increases the losses. Secondly, the sizing process for the module capacitance and the arm inductance is describ

高压直流输电（HVDC），是利用稳定的直流电具有无感抗，容抗也不起作用，无同步问题等优点而采用的大功率远距离直流输电。输电过程为直流。-High voltage direct current (HVDC) transmission is the use of stable DC has no inductance, Rongkang doesn t work, without synchronization, etc. the high power long-distance HVDC tran
