description | The invention discloses an ANPC three-level inverter driving fault self-recovery method and system. The method comprises the steps that all driving modes of six switching tubes in a single-phase bridge arm of an ANPC three-level inverter are acquired; according to the correct driving logic of the six switching tubes and the current direction of the single-phase bridge arm, finding out a correct driving mode and a correct driving sequential logic; and performing mode identification on the currently received driving signal, if the driving signal is correct, performing normal output, and if the driving signal is not correct, performing fault self-recovery by combining the current direction signal of the current bridge arm. According to the method, the wrong driving signal of the ANPC type three-level inverter can be accurately identified, fault self-recovery is carried out, inverter damage caused by the wrong driving signal is effectively avoided, and the reliability of equipment operation is improved.
