With the second situation, fixed output, your options open up even more.

对于输出固定的第二种情况，选择的范围更大了。

It can achieve a fixed output of DC voltage in the universal input range of ac 80 ~ 265 V. It owns the advantages of high efficiency, low total harmonic distortion, PF near to 1.

该方案能在80 ~ 265 V宽输入电压范围内得到稳定直流电压输出，具有效率高、总谐波畸变率低、功率因数接近为1等特点。

This rests on the notion that there is a fixed ceiling for output, rising over time, so any shortfall against potential is a permanent loss.

Second, the input-output model assumes fixed relationships over the time of the forecast horizon.
