| titleOfInvention | A three-level inverter that protects the DC bus voltage from overshoot when paralleling |
| abstract | The invention discloses a three-level inverter that protects the DC bus voltage from overshoot when paralleling. The invention distributes the duty ratio of the carrier signal Vn output by the three-level current loop near the zero-crossing point. Improvement, to prevent the occurrence of overshoot of the energy storage inverter and improve the reliability of the droop algorithm wireless parallel; generation and distribution; when the overshoot signal will cause the bus voltage high voltage protection, λ=‑1, assigning it a small negative number -0.0001 will force the negative half cycle near the zero-crossing point to continue to operate, forcing S1 and S2 to turn off, making the S3 is normally open, and S4 is open with a very small duty cycle, so that the original overshoot current can reach the neutral line through S3 and D2 to complete the freewheeling, which plays a role in protecting the DC bus voltage. |
