Non-Isolated Multi-Port High Gain Interleaved Boost DC-DC Converter for Base Transceiver Station Application

This paper addresses a multi-port interleaved boost converter for base transceiver station (BTS) load with photovoltaic (PY) as a source and battery as backup energy storage device. The converter is designed to control the power flow from PV, battery and BTS load, and to regulate BTS load for 48V. In this paper, different modes of operations of converter are studied which depends on the availability of power from source and the battery. Further, steady state analysis and average state space equations of the proposed converter have been analysed. Furthermore, small signal modelling of the converter is carried out for the proposed converter. The MATLAB/SIMULINIC based analysis has been (a) carried out to verify the proper operation of the converter.
