Abstract:
A current limiting control method for a three-level inverter, comprising the following steps: S 1 . when a current output from a bridge arm is greater than or equal to a current limiting threshold and a received overcurrent signal is enabled, first turning off the main switch transistors and then turning off the auxiliary switch transistors; S 2 . when the current output from the bridge arm drops to lower than the current limiting threshold and the received overcurrent signal is disabled, turning on the auxiliary switch transistors; S 3 . when the received overcurrent signal is disabled and a next PWM effective edge of the main switch transistors arrives, turning on the main switch transistors. The present invention relates also to a current limiting control device for a three-level inverter. By implementing the present invention, it is possible to ensure voltage waveform quality and reduce switching loss.

Claim (Index 2):
The current limiting control method for a three-level inverter according to  claim 1 , characterized in that the step S 2  further comprises:\n S 21 . when the current output from the bridge arm drops to lower than the current limiting threshold and the received overcurrent signal is disabled, turning on the auxiliary switch transistors after elapse of a first delay time; \n S 22 . when the current output from the bridge arms rises to greater than or equal to the current limiting threshold and the received overcurrent signal is enabled, again turning off the auxiliary switch transistors and no longer turning on the auxiliary switch transistors within this switching cycle.
