Abstract

The burn-in test has been regarded as a feasible approach for quality certification of new UPS products. In this paper, we proposed a new approach of circulating current method for UPS burn-in testing with energy recovery. With the application of this method, the testing power can be recycled for reuse such that the experimental cost can be largely reduced. Besides, the proposed method is useful to restrict the degree of harmonic pollution that may affect the utility grid. Therefore, electric power quality can be also better ensured. This method has been validated through the simulation study. Simulation results help consolidate the feasibility of the approach for the applications considered.
