BASIC CABLE CHARACTERISTICS PART II Carl Landinger
... Cables installed in pipe or conduit made of magnetic materials will have a further increase in ac resistance. The increase is approximated by multiplying Ycs and Ycp by 1.7 resulting in the formula Rac = Rdc·[1 + (Ycs + Ycp)·1.7] This multiplying factor is applied whether the cables are in the cradl ...

a unity power factor bridgeless isolated cuk converter
... This paper presents a power factor correction (PFC)-based bridgeless isolated Cuk converter-fed brushless dc (BLDC) motor drive. A variable dc link voltage of the voltage source inverter (VSI) feeding the BLDC motor is used for its speed control. This allows the operation of VSI in fundamental frequ ...
