In this paper, we deal with photovoltaic power generation using cascaded H-bridge inverter fed from interleaved soft switching boost converter. The proposed H-bridge inverter approach employs the minimum number of devices. In this approach, five-level H-bridge inverter will reduce the harmonic distortion; it improves the output voltage rating and minimize the necessity of filter. Multisampling technique is adopted for reducing the switching delay and it maximizes the performance of controller. Zero Voltage and Zero current switching methods are used to decrease the switching loss in DC/DC conversion. Interleaved operation of boost converter will reduce the switching losses. Suitable resonant components has been designed and current ripples are minimized significantly. In this paper, results of the complete power conditioning system has been analyzed, verified and presented using MATLAB/SIMULINK software tools. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.
