同时，利用两级敏感放大器的层次式结构降低数据线的电压幅度，进一步降低了功耗。
In addition, the sense amplifier's hierarchical architecture can be used to reduce the data bus voltage amplitude, which further reduces the power dissipation.
该分布式电源系统采用高频母线形式，原边电路采用双管正激电路，电压前馈控制，后级利用磁放大器精确控制。
The primary circuit has the form of double switch forward of feedforward control, the second circuit used the magnetic amplifier as the post regulator.
在功率输出级采用OCL互补对称功率放大电路，并对该功放电路增加电压负反馈，使得输出的正弦电压信号平滑而稳定。
At the power output, OCL complementally and symmetrical power amplifier is adapted. The output sine voltage becomes smooth and stable by adding voltage-negative-feedback to power amplifier.
