Abstract :
This paper presents the design of an on-chip integrated power management architecture with Maximum Power Point Tracking (MPPT) for Photovoltaic (PV) solar system. The system is developed in order to extract higher power for PV system under partial shading and other mismatching conditions. The MPPT circuit is implemented in 0.35μm Complementary Metal-Oxide-Semiconductor (CMOS) technology. The on-chip system utilizes a high-efficiency synchronous DC-DC boost power converter and analog Ripple Correlation Control (RCC) circuit for MPPT control. The 2400μm×5000μm developed Integrated Circuit (IC) is connected to a solar cell with 0.5V nominal output voltage and 5A output current. A peak efficiency of 92% is achieved. The design of the power stage and analog RCC MPPT algorithm circuit are presented and examined in this paper.
