摘要：
A high gain quadratic boost converter with continuous input current is proposed in this paper.The ripple in the current is eliminated in the designed two-phase interleaved converter by operating the input side switches at the fixed duty cycle of 0.5. The transformerless converter operation with high gain makes the converter appropriate for integrating photovoltaic (PV) power to isolated DC microgrid. The common intermediate capacitor reduces the component count and voltage stress on the input side switches; thus, achieving high efficiency at a lower cost. The Proposed interleaved quadratic boost converter is ideal for PV power extraction as it exhibits no input current ripple and has high input current handling capability. A 1000 W two-phase interleaved prototype of the converter is designed, developed, and analyzed to verify its working principle. The performance testing is done with the laboratory prototype with a DC microgrid of 230 V connected to the converter's output.
