Abstract :
It is essential that a UPS transfer between line-mode powering and inverter-mode powering without any significant output transients. This paper uses a SPICE model for the ferroresonant transformer to discuss the operation during these transitions. Model predictions are compared with laboratory data obtained from a microprocessor-controlled ferroresonant UPS
