Abstract: A novel quadratic boost converter capable of delivering a high output voltage is introduced. Dc-dc operation in continuous conduction mode (CCM) and discontinuous inductor current mode (DICM) are analyzed. A simple and versatile feedforward (FF) circuit is proposed in order to be used with the new converter when operated in CCM. Another application is the use of the converter as a power factor correction (PFC) circuit. At low power levels DICM operation is chosen because of the converter natural capability of emulating a resistor at low frequency. Design equations, simulation results and merit parameters are presented for all the investigated topologies.
