Abstract

In this paper, a battery-integrated boost converter for module-based series connected photovoltaic (PV) system is analyzed. Each PV module has its own battery and DC/DC converter. The converter achieves maximum power point tracking (MPPT) and battery charging. Application of proposed converter to module-based series connected PV system can maintain string voltage and save an additional voltage amplification stage. Steady-state analysis of the converter to determine the power flow equations is presented. Three advantages comparing with the conventional series connected boost converter are reported. Simulation and experimental results of a laboratory prototype are presented.
