With the digital PI modulation the outputvoltage of the power supply is very precision and stabilization.
采用数字PI调节，提高了稳态时输出电压的精度和稳定性。

One disadvantage of this method of stabilization is the additional output noise and offset voltage caused by increased amplification of input-referred voltage noise and input offset voltage.
这种稳定方法的一个不足是：输入端的有关电压噪声和失调电压增大会额外地增加输出噪声和失调电压。

For the problem of voltage compensation, the design of microprocessor control system used in voltage compensation controlled voltageoutput availably, and the stabilization of the system is increased.
