A new bridgeless Cuk PFC converter driving a permanent magnet brushless DC motor drive is proposed here. In the case of a conventional BLDCM drive system there will be a rectifier and a PFC converter connected to the drive through a voltage source inverter. In this paper, it is replaced by a bridgeless PFC Cuk converter and the voltage source inverter connected to the PMBLDCMD. This improves the efficiency of the drive as well as maintains a unity power factor. This is because of the bridgeless topology introduced which does not have an input diode bridge rectifier.
