It introduces the principle of voltage inverter, analyzed the reason of distortion of output voltage and current wave form, as it is loaded with hysteresis synchronous motor.
本文介绍电压逆变器的原理，分析带上磁滞同步电动机这一负载后逆变器输出电压电流波形畸变的原因。

Compared with asynchronous sampling mode, synchronous circuit has the advantages of short sampling period and small distortion.
与异步采样电路相比，同步采样电路具有周期短、失真小等优点。
