Power Factor correction using Boost Converter technique Engineering essay
The need for solid-state ac-dc converters to improve power quality in terms of power factor correction PFC, reduced total harmonic distortion at the input of the ac mains and precisely controlled dc output. It is known that the switching power supply is the cornerstone of power conversion technology. Charging the battery requires an effective and convenient DC-DC converter. For the battery charging cycle, most EVs use buck-boost converters. Buck and boost converters are simple and efficient, but cannot provide. In theory, a bridge diode and a capacitor bank can convert an AC sine wave into a DC signal, but the source current appears spiky and has a power factor much less than unity. To correct the distortion and phase shift of the source current, a PFC stage with power factor correction is usually used in a power supply. To improve the power density of PFC converters with power factor correction, an integrated structure for both electromagnetic interference filters and boost inductors is presented with a flexible multi-layer foil integration technique. The electromagnetic analysis of the proposed structure is given, and the calculations of the. Generally, a boost converter in current conduction mode is used for an active PFC, power factor correction. In particular, an interleaved PFC boost converter is used to create a compact format. make a.
