Abstract

A novel technique for the improvement of power conversion efficiencies in PV systems with battery back-up is presented, analyzed and applications for this Parallel Power Conversion Technique (PPCT) are suggested. The PPCT may increase the available energy in an existing PV system, employing a polarity changing Maximum Power Point Tracker (MPPT), or a split battery system, without adding anything to the PV system. This is accomplished by rewiring the PV system, utilizing the PPCT. The PPCT may also be used to reduce the power rating of the PV array in new PV systems with battery back-up. This PPCT is also illustrated in a compound converter and a new topology for a MPPT. Experimental results employing this PPCT are presented.
