In this paper, a solution to alleviate mutual interference between the loads during load transients is presented for dual-output power server system. The output DC bus of conventional PFC (Power Factor Correction) system is modified to have independent DC bus for such tenacity. The Boost PFC converter is replaced by Interleaved Boost (IB) PFC converter and furthermore modified at the output end without...
This paper introduces a single-stage active power factor correction (PFC) AC-DC converter which provides almost unity power factor and minimizes the THD to 7.4 %. For a constant DC output voltage a single phase diode bridge rectifier with a large output capacitor is considered in this paper. This standard topology has a shortcoming of introducing lower order harmonics and become cause of poor power...
This paper exhibits a relative investigation of different governing methods on a shunt active power filter for harmonics and VAR compensation for a balanced three phase system connected to a composite load. Three techniques, namely, instantaneous active and reactive power method, instantaneous active and reactive current control method and unit vector template method are used for the source current...
In past few years, multilevel inverters have shown considerable advantages over traditional two-level inverters in a majority of the high power high voltage and medium voltage industrial applications. As a consequence, the cascaded multilevel inverter (CMI) configuration has grabbed tremendous interest in the power industry. Now-a-days, with the increasing usage of power electronic devices by industrial,...
