Abstract：In this paper, a control method is proposed for high voltage inverter with cascaded cell topology to deal with short-time drop or even interruption of grid voltage. The control method can avoid the output over-current and power cell under-voltage faults when grid voltage drops or even interrupts for a short time, and can automatically recover to the normal state when grid voltage recovers. Finally, the application of the control method in the compressor station of long distance gas pipeline is introduced.
