COUPLED INDUCTOR RESONANT SWITCHED CAPACITOR VOLTAGE EQUALIZER FOR PHOTOVOLTAIC PARTIAL SHADING COMPENSATION

Switched capacitor converters play an important role in various applications power electronics. Voltage equalizers are one of them, and have been applied for partial shading compensation photovoltaic systems. In other works, the switched capacitor, improved with addition a small inductor, becoming resonant converter many advantages compared to capacitor. However, this can still be aspects, rather its effective resistance, equalized voltage drop, current stress. paper, novel Coupled Inductor Resonant Capacitor equalizer is proposed. The comparison between all circuits here studied developed through simulation results. Also, proposed circuit experiment results presented. At end, conclusions summing paper contribution made.
