Abstract |
|
Power factor and harmonics are very important in power system. Low power factor and high THD affects the system efficiency, to improve this with the help of advanced power electronics devices, different PFC topologies are implemented for the ups system. Pf is improved by auxiliary winding of the fly back converter, dc-dc converter is operated in high switching frequency input current conduction angle is increased and the harmonics is reduced. In this paper low THD high efficiency, high power factor, less size are achieved. The developed topology is simulated in MATLAB /Simulink 2013 software and results are obtained. |
