如果输出电压小于预定的电压电平，则开关电路部分将增强的控制信号传输到调节电路。

If the output voltage is less than the predetermined voltage level, the switching circuit portion transmits an enhanced control signal to the regulation circuit.

增强的控制信号将输出电压快速增加到至少最小期望电平。

The enhanced control signal quickly brings the output voltage up to at least the minimum desired level.

在恶劣电力线通信环境下，只有努力提高自动增益控制(agc)水平，才能实现信号电平的稳定。

In poor PLC communication environment, the stability of the signal can only be realized by improving the level of Automatic Gain Control (AGC).
