This is not really a disadvantage, but a difference in the way the two types of voltage are measured, AC is measured in RMS while Dc is measured as Peak Voltage.

这不是一个真正的缺点﹐而是两者的计量方式不同，交流电压是以有效值来计量而直流电压是以其峰值来计量的。

The main function of rectifier circuits is to convert AC to DC.

整流电路的主要作用是将交流电压转换成直流电压。
