The paper proposes an interleaved high gain boost converter with quadratic function for high power PV system. The proposed converter employs a diode-capacitor (DC) snubber circuit designed to absorb the transient spike generated by the coupled inductor leakage inductance, reduce excess voltage stress and boost the output voltage once again. This design uses interleaved technology for the high gain boost converters to reduce power losses and save cost. This paper will introduce interleaved technology in the proposed high power and high gain boost converter. Experimental and simulation results are used to verify the design and performance. The 500 W interleaved high gain boost converter design was measured to 93.1% efficiency. The designed interleaved conversion architecture with the maximum power reaches 1 kW with average converter efficiency over 90%.
