Abstract

The `Deltafly', a circuit belonging to a family of two-stage, three-phase power factor correction circuits, is proposed. A new space vector analysis method using the average current over a switching cycle is used for studying the discontinuous conduction mode operation of the circuit. The `Deltafly' represents a combination of the boost-delta and flyback circuits, with features depending on the inductance ratio of the two stages, and with component stress sharing
