Current distortion suppression method and device, controller, rectification system and storage medium

The invention provides a current distortion suppression method and device, a controller, a rectification system and a storage medium. The method comprises the following steps: monitoring a modulation voltage waveform of a target phase of the Vienna rectifier; wherein the target phase is any one of the three phases of the Vienna rectifier; and if it is monitored that the modulation voltage waveform of the target phase is in a zero-crossing interval, a switching tube pulse corresponding to the target phase is controlled to be locked, so that the voltage of the modulation voltage waveform of the target phase is zero in the zero-crossing interval, and the zero-crossing interval takes the zero-crossing point of the standard modulation voltage waveform of the target phase as the center. According to the invention, the current zero-crossing distortion of the Vienna rectifier can be suppressed. 本发明提供一种电流畸变抑制方法、装置、控制器、整流系统及存储介质。该方法包括：监测Vienna整流器的目标相的调制电压波形；其中，目标相为Vienna整流器三相中的任意一相；若监测到目标相的调制电压波形处于过零区间，则控制目标相对应的开关管脉冲闭锁
