摘要
The operating conditions of UPS inverters and the fact that the load is unknown lead to great difficulties in fault diagnosis. This paper proposes the use of a fault diagnosis algorithm based on estimated pole voltage error for UPS inverters based on the 3-level Neutral-Point-Clamped topology. This algorithm is independent from the load and is not affected by unbalanced three-phase operation. This algorithm provides very fast and reliable results and requires no additional sensors or hardware. Simulation results are presented to demonstrate the algorithm's speed and robustness.
