这个之外这搭所谓直流电压被称作“浮动电压”(floating voltage),因为它们其实不消地电位作参考。有一些设备如nagra录音机以及前边提到的shure调音台可以选择用t-power还是传统的幻象供电。

浮动电压的电池适用于被裁定为紧缩0.8%宽容和可编程充电电流通过外部电阻到地。
The float voltage applied to the battery is held to a tight 0.8% tolerance, and charge current is programmable using an external resistor to ground.
但其存在浮动电容器的电压失配问题，尤其在低开关频率时尤为显著。
But the unbalance of the floating capacitor voltage can be a problem, especially at low switching frequencies.
本文研究了静止无功补偿器的调节特性及其对减少系统电压浮动、改善系统稳定的效果。
