Study of AC-DC converter

Abstract

The modern electronic devices operate with low DC output voltage. The AC utility supply needs to be converted and step down to a suitable DC voltage. During earlier days, the converters were huge in size and were expensive too. A remarkable reduction in size and price was possible due to the invention of switch mode power supply. This goal by expanding the power density which is achievable by decreasing the size of the passive/energy storage components such as the inductors, capacitors and the transformer. For better utilization of the existing electric energy the entire power system should be operated at high efficiency for that reason now a days we use different types of converter. In this thesis, study of the AC-DC converters are carried out along with relevant simulations to realize the deeper understanding on the topic Therefore, the main objective of this research is to study in detailed the working principles and applications of linear power supply in ac to dc converter.
