The complexity of control strategy is equivalent with that of ac-dc-ac converter, and the voltage transfer ratio is theoretically up to 0.955.

其控制算法与交—直—交变换器控制算法的复杂度相当，电压传输比在理论上可达到0.955。

Some people, however, question that standard because over long distances high-voltage DC lines suffer lower losses than AC.

现在有人开始质疑这一标准的适用性，因为在远距离输电的情况下，采用高压直流(HVDC)要比高压交流损耗小。

FORBES: Was Bell Labs Overrated?

Just as AC beat DC, the audio cassette beat 8-track and VHS beat Betamax, Qwerty won the format war.
