This paper proposes a new configuration for solar energy conversion systems. One challenging issue of the photovoltaic (PV) systems is partial shading, and in this paper Module Integrated Converters (MIC) are used to overcome this problem in PV arrays. A few boost converters are employed as MICs to mitigate the shading effect. Furthermore, to reduce the cost and to increase the system performance the B4 inverter is used. This inverter is a four-switch, three-phase inverter. To validate the performance of the proposed system and simulation results, a typical prototype has been made and experimental results have been carried out. The results confirm the effectiveness of the circuit in mitigating the effects of partial shading
