Abstract
A new innovative concept in AC/DC cell that transfers energy to the output side directly from the input line, rather than from the storage capacitor in power factor correction (PFC) cell during the period that the line voltage exceeds a preset value. The new concept is based on providing additional winding coupled to the DC/DC transformer connected to the rectified input side to provide a path for the energy transfer from the line to transfer to the output directly (Boost cell) or to be stored in the output transformer (Flyback cell).
