摘要

A new parallel processing uninterruptible power supply (UPS) configuration is proposed in this paper. It provides active power line conditioning to minimize mains current distortion. This performance is superior to a conventional UPS. A prototype has been implemented and tested to verify its performance. The experimental results show that the input power factor of the proposed UPS is nearly unity, and the total harmonic distortion (THD) of the input current under nonlinear loading is only 3.618% for a mains voltage with THD of 1.633%.
