RESUMO

This work presents the complete study regarding a non-isolated online Uninterruptable Power Supply (UPS), which employs a PFC boost converter associated with a passive resonant cell operating at high frequency. The analysis includes the operating principles, mathematical development and design procedure of the proposed system. It can be demonstrated that the use of a resonant cell and average current mode control provides satisfactory performance in the achievement of soft switching and unity power factor, respectively. Additionally, desirable features such as high efficiency, low cost, and also reduced weight and size are obtained.
