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 3):
The current limiting control method for a three-level inverter according to  claim 1 , characterized by further comprising:\n S 4 . switching, based on the number of switching cycles during each of which current limit switching of the auxiliary switch transistors has occurred twice, a switching frequency of the auxiliary switch transistors within each switching cycle.
