该系统产生的电流为直流电，所以用来驱动本地的直流点装置比将其转化为交流电输入电网来的更有效率。
The system generates a direct current, so using it to power DC devices locally is more efficient than switching to the alternating current needed to feed it back to the grid.
如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured.
电信号被用电子的方法放大，即利用输入放大器的交流电能将信号的功率放大。
The electrical signal is amplified electronically, with an increase in signal power occurring at the expense of the input AC power to the amplifier.
