Implementation of energy stored for TC nano grid with power factor correction converter

Abstract

In the recent years DC Nano grid has become more popular which serves as a replacement for the AC-grid due to the DC characterized loads and more distributed power generation sources. The advantage of using DC Nano-grid is that, it provides safety by providing reliable grounding for residential. In this paper, a dual Buck-Boost AC/DC converter to be used in the united grounding configuration, based on DC Nano-grid with three terminal outputs on existing low power AC system is designed by using the proposed converter. The main aim of the work is to design a converter with high power factor and less steady state error. To reduce the errors and faults unidirectional grounding is implemented and the power factor is corrected using phase lock loop.The modeling of the system and the working of the proposed converter are explained and validated with Simulations results.
