This paper presents a comparative study between H5, HERIC transformer-less inverters when they are utilized in PV system feeding a standalone load. Pulse width modulation and selective harmonic elimination techniques are applied for each inverter. The comparison between the inverters is carried out based on inverter conduction losses, filter size and PV leakage current. A dc-dc boost chopper is used to raise the PV-array voltage to a suitable value to meet load requirements. The boost converter is controlled through the incremental inductance maximum power point tracker which is utilized to maximize the power delivered from the PV-array.

This paper proposes a switching strategy for Cascaded H-bridge (CHB) multilevel inverter for photo voltaic (PV) power generation systems under nonuniform illuminating conditions. In order to minimize the switching frequency, selective harmonic elimination (SHE) technique is used to determine the inverter switching pattern. As the DC voltages are unbalanced and vary from time to time, the switching pattern has to change dynamically. How to implement the dynamic switching pattern by using a field programmable gate array (FPGA) is described in this paper. Several simulated and experimental results are included in this paper to show the effectiveness of the proposed method.
