提出了一种基于二电平和三电平电压源换流器的VSC-HVDC系统效率的解析计算方法。该方法使用VSC转换器电流的平均值和均方根来估计转换器中的转换损耗（传导损耗和开关损耗）。剩余的功率损耗（由于I2 R引起的DC电缆传输损耗、耦合Transformer中的损耗和AC谐波滤波器损耗）使用常规的公知方法来评估。分析得到的结果证实了数字仿真。
An analytical method to calculate the efficiency of VSC-HVDC links based on two-level and three-level VSCs is presented. The method uses the average and root mean square of the VSC converter current to estimate the conversion losses in the converters (conduction and switching losses). The remaining power losses (DC cable transmission losses due to I2R, the losses in the coupling transformer, and AC harmonic filter losses) are evaluated using conventional well-known methods. Results obtained analytically are confirmed by digital simulations.
