An analog signal is composed of four basic components: DC and AC magnitudes, frequency, and phase.
模拟信号由直流和交流分量、频率和相位四部分组成。
Therefore it can be seen that it will "smooth" the "twice mains frequency DC" into a near constant DC voltage.
因此它可以把“两倍于电源频率的直流电”进行“平滑化处理”，成为一个接近恒定的直流电。
The DC into AC current adjustable frequency that the inverter on.
将直流变为频率可调的交流电流就称逆变。
